Space News: NASA’s Webb reveals smallest asteroids yet found in main asteroid belt

NASA’s powerful James Webb Space Telescope includes asteroids on its list of objects studied and secrets revealed.

A team led by researchers at the Massachusetts Institute of Technology in Cambridge repurposed Webb’s observations of a distant star to reveal a population of small asteroids — smaller than astronomers had ever detected orbiting the Sun in the main asteroid belt between Mars and Jupiter.

The 138 new asteroids range from the size of a bus to the size of a stadium — a size range in the main belt that has not been observable with ground-based telescopes.

Knowing how many main belt asteroids are in different size ranges can tell us something about how asteroids have been changed over time by collisions.

That process is related to how some of them have escaped the main belt over the solar system’s history, and even how meteorites end up on Earth.

“We now understand more about how small objects in the asteroid belt are formed and how many there could be,” said Tom Greene, an astrophysicist at NASA’s Ames Research Center in California’s Silicon Valley and co-author on the paper presenting the results. “Asteroids this size likely formed from collisions between larger ones in the main belt and are likely to drift towards the vicinity of Earth and the Sun.”

Insights from this research could inform the work of the Asteroid Threat Assessment Project at Ames. ATAP works across disciplines to support NASA’s Planetary Defense Coordination Office by studying what would happen in the case of an Earth impact and modeling the associated risks.

“It’s exciting that Webb’s capabilities can be used to glean insights into asteroids,” said Jessie Dotson, an astrophysicist at Ames and member of ATAP. “Understanding the sizes, numbers, and evolutionary history of smaller main belt asteroids provides important background about the near-Earth asteroids we study for planetary defense.”

The team that made the asteroid detections, led by research scientist Artem Burdanov and professor of planetary science Julien de Wit, both of MIT, developed a method to analyze existing Webb images for the presence of asteroids that may have been inadvertently “caught on film” as they passed in front of the telescope.

Using the new image processing technique, they studied more than 10,000 images of the star TRAPPIST-1, originally taken to search for atmospheres around planets orbiting the star, in the search for life beyond Earth.

Asteroids shine more brightly in infrared light, the wavelength Webb is tuned to detect, than in visible light, helping reveal the population of main belt asteroids that had gone unnoticed until now.

NASA will also take advantage of that infrared glow with an upcoming mission, the Near-Earth Object, or NEO, Surveyor. NEO Surveyor is the first space telescope specifically designed to hunt for near-Earth asteroids and comets that may be potential hazards to Earth.

The paper presenting this research, “Detections of decameter main-belt asteroids with JWST,” was published Dec. 9 in Nature.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Published: 24 December 2024
LAKE COUNTY, Calif. — A Clearlake Oaks woman died early Tuesday after she was involved in a vehicle collision with a semi truck.

The California Highway Patrol’s Clear Lake Area office did not release the name of the 76-year-old woman in its Tuesday afternoon report on the crash pending the notification of her next of kin.

The CHP’s report said its officers responded to reports of a traffic crash on state Route 53, south of state Route 20 near Clearlake Oaks, at approximately 6:26 a.m. Tuesday.

When they arrived, the CHP said its officers determined that the female driver from Clearlake Oaks was driving a 2000 Lexus RX3 southbound on state Route 53.

Also traveling southbound on state Route 53 was Javier Gomez Jimenez, 57, of Williams, driving a 2015 Peterbilt truck tractor, the CHP said.

For reasons that the CHP said are still undetermined, the woman made a U-turn from the southbound shoulder ahead of Gomez Jimenez, resulting in a broadside crash.

The woman died of her injuries at the scene, the CHP said.

Gomez Jimenez remained on scene and was uninjured. Both drivers were believed to be wearing their seat belts, according to the CHP report.

The CHP said it’s currently unknown if drug or alcohol impairment were factors in the crash.

Conditions at the time were dark and wet, the report said.

Resources from the Lake County Sheriff’s Office, Lake County Fire Protection District, Caltrans and Alvarez Towing responded to the scene and assisted the CHP with the investigation, the CHP said.

The CHP said traffic impact on state Route 53 was minimal following the incident.

Thompson, Padilla, Lamalfa press for swift implementation of law to deliver tax relief for wildfire survivors

Written by: LAKE COUNTY NEWS REPORTS
Published: 24 December 2024
On Monday, Rep. Mike Thompson (D-CA-04) and U.S. Sen. Alex Padilla (D-CA) and Representative Doug LaMalfa (R-CA-01) released a letter urging the Internal Revenue Service to take immediate actions to implement their bipartisan legislation providing critical tax relief for wildfire victims.

President Biden recently signed the Federal Disaster Tax Relief Act into law.

The Federal Disaster Tax Relief Act supports the nearly 70,000 survivors who suffered significant losses during three major federally declared California fires in 2015, 2017 and 2018 who have received related settlement payments, as well as future recipients of other wildfire settlements related to federally declared fires.

Many California wildfire survivors have already been taxed on their settlement payments, with some even losing access to certain federal benefits as a result of their compensation wrongly being considered income.

The requests outlined by Thompson, Padilla, and LaMalfa are instrumental in delivering the full relief these wildfire survivors deserve.

“[M]any Californians that received compensation have already been taxed on these payments in previous calendar years. This has significantly and unfairly hindered their ability to rebuild after devastating loss,” wrote the lawmakers. “Now that President Biden has signed this bill into law, the IRS must take every action available to provide clarity and guide taxpayers through the changes to the tax treatment of such payments.”

“Californians who have suffered inconceivable losses as a result of utility-caused wildfires have waited too long for tax relief,” continued the lawmakers. “We appreciate your attention to this matter, and we look forward to working with you to ensure that wildfire survivors have access to their full settlements and federal benefits.”

Specifically, the lawmakers recommended that the IRS take the following urgent steps in implementing Section 3 of the Federal Disaster Tax Relief Act:

• Prioritize the drafting and approval of FAQs: The lawmakers asked the IRS to quickly finalize relevant FAQs so that impacted taxpayers can begin applying for refunds.
• Make necessary technical changes to IRS’ systems: Sec. 3(e) of the Federal Disaster Tax Relief Act extends the period of limitation for credit or refund claims allocable to the exclusion of settlement payments to one year after the date of enactment. To implement this, the IRS must make technical updates to process applications and issue approved refunds online.
• Maximize community outreach and education: The lawmakers requested the IRS provide targeted outreach and work with community partners to ensure that all eligible taxpayers are aware of these tax code changes.
• Ensure all federal benefits are restored: Many wildfire survivors who would have otherwise qualified for certain federal benefits were wrongfully denied because their income was artificially inflated from the settlement payments. The lawmakers urged the IRS to ensure taxpayers are also made whole on federal benefits, such as Affordable Care Act premium assistance and Child Tax Credit and Earned Income Tax Credit payments.

The full text of the letter is below.


Dear Secretary Yellen and Commissioner Werfel:

As members of the California delegation representing wildfire survivors that have received settlement payments for losses suffered during the three major California fires in 2015, 2017, and 2018, we write to urge the Internal Revenue Service (IRS) to take immediate action on implementing Section 3 of the Federal Disaster Tax Relief Act. President Biden recently signed our legislation to exempt such compensation from gross income for income tax purposes.

As you know, our tax code fails to clarify that disaster settlement funds, which are already insufficient in covering the full cost of losses, are neither income nor asset. Unlike those impacted by the fires that ravaged southern Oregon and Maui, many Californians that received compensation have already been taxed on these payments in previous calendar years. This has significantly and unfairly hindered their ability to rebuild after devastating loss. Now that President Biden has signed this bill into law, the IRS must take every action available to provide clarity and guide taxpayers through the changes to the tax treatment of such payments. Specifically, we ask that you:

Prioritize the drafting and approval of FAQs: Our understanding is that the provisions in this bill are self-enacting and do not require Department of the Treasury or IRS rulemaking. In order for impacted taxpayers to begin the refund process as soon as possible and receive the funding necessary to finance continued recovery, we ask that the IRS expedite the development of relevant FAQs.

Make necessary technical changes to IRS’ systems: Sec. 3(e) extends the period of limitation for credit or refund claims allocable to the exclusion of settlement payments to one year after the date of enactment. The IRS should make the necessary technical changes to current systems to allow for the processing of applications and issuance of approved refunds online. This will be critical for allowing a seamless and quick return process to put money back in the hands of wildfire survivors.

Maximize community outreach and education: Successful implementation of this bill will require targeted outreach to impacted taxpayers so that all eligible individuals are made aware of these changes to the tax code. The IRS must utilize every available resource to train and work in collaboration with community partners to ensure that all eligible taxpayers are able to submit refund applications.

Ensure all federal benefits are restored: Those who would have otherwise qualified for certain federal benefits administered by the IRS were denied because their gross income was artificially inflated as a result of the settlement payments. The IRS should ensure that, in filing for credit or refund, taxpayers also receive retroactive federal benefits (e.g., Affordable Care Act premium assistance, Child Tax Credit and Earned Income Tax Credit payments, etc.) from these taxable years. We also ask that IRS work with other federal agencies to ensure taxpayers can apply for any non-IRS administered benefits.

Californians who have suffered inconceivable losses as a result of utility-caused wildfires have waited too long for tax relief. We appreciate your attention to this matter, and we look forward to working with you to ensure that wildfire survivors have access to their full settlements and federal benefits.

How to avoid the latest generation of scams this holiday season

Imagine this: Two days before your family holiday party, you get a text about an online order you placed a week ago, saying the package is at your door. It comes with a photo – of someone else’s door. When you click the attached link, it takes you to the online store, where you enter your username and password. Somehow that doesn’t work, even though you answered your security questions.

Frustrated, you call customer service. They tell you not to worry since your package is still on the way. You receive your package a day later and forget all about the earlier hassle. In the end, it was just a mistake.

You are unaware of the terrifying thing happening in the background.

You’ve fallen for a classic package-delivery scam, and a form of “smishing,” or SMS phishing. And you’re not alone. One in three Americans have fallen victim to cybercrime, according to a 2023 poll. That’s up from 1 in 4 in 2018. As cybersecurity researchers, we want to spread the word to help people protect themselves.

Old-fashioned threats haven’t disappeared – identity thieves still steal wallets, dumpster dive for personal information and skim cards at ATMs – but the internet has made scamming easier than ever.

Digital threats include phishing attacks that use fake emails and websites, data breaches at major companies, malware that steals your information, and unsecured Wi-Fi networks in public places.

A whole new world of scams

Generative AI – which refers to artificial intelligence that generates text, images and other things – has improved dramatically over the past few years. That’s been great for scammers trying to make a buck during the holiday season.

Consider online shopping. In some cases, scammers craft deepfake videos of fake testimonials from satisfied “customers” to trick unsuspecting shoppers. Scam victims can encounter these videos on cloned versions of legitimate sites, social media platforms, messaging apps and forums.

Scammers also generate AI-cloned voices of social media influencers appearing to endorse counterfeit products and create convincing but fraudulent shopping websites populated with AI-generated product photos and reviews. Some scammers use AI to impersonate legitimate brands through personalized phishing emails and fake customer service interactions. Since AI-generated content can appear remarkably authentic, it’s become harder for consumers to distinguish legitimate online stores from sophisticated scam operations.

But it doesn’t stop there. “Family emergency scams” exploit people’s emotional vulnerability through deepfake technology. Scammers use AI to clone the voices of family members, especially children, and then make panic-inducing calls to relatives where they claim to be in serious trouble and need immediate financial help.

Some scammers combine voice deepfakes with AI-generated video clips showing the “loved one” in apparent distress. These manufactured emergency scenarios often involve hospital bills, bail money or ransom demands that must be paid immediately. The scammer may also use AI to impersonate authority figures like doctors, police officers and lawyers to add credibility to the scheme.

Since the voice sounds authentic and the emotional manipulation is intense, even cautious people can be caught off guard and make rushed decisions.

How to protect yourself

Protecting yourself against scams requires a multilayered defense strategy.

When shopping, verify retailers through official websites by checking the URL carefully – it should start with the letters “HTTPS” – and closely examining the site design and its content. Since fake websites often provide fake contact information, checking the “Contact Us” section can be a good idea. Before making purchases from unfamiliar sites, cross-reference the business on legitimate review platforms and verify their physical address.

It’s essential to keep all software updated, including your operating system, browser, apps and antivirus software. Updates often include security patches that fix vulnerabilities hackers could exploit.

For more information on the importance of software updates and how to manage them, check out resources like StaySafeOnline or your device manufacturer’s official website. Regular updates are a crucial step in maintaining a secure online shopping experience.

Make sure you only provide necessary information for purchases – remember, no one needs your Social Security number to sell you a sweater. And keeping an eye on your bank statements will help you catch any unauthorized activity early. It may seem like another chore, and it probably is, but this is the reality of our digital world.

To protect against family emergency scams, establish family verification codes, or a safe word, or security questions that only real family members would know. If you do get a distressed call from loved ones, remain calm and take time to verify the situation by contacting family members directly through known and trusted phone numbers. Educate your relatives about these scams and encourage them to never send money without first confirming the emergency with other family members or authorities through verified channels.

If you discover that your identity has been stolen, time is critical. Your first steps should be to immediately contact your banks and credit card companies, place a fraud alert with the credit bureaus, and file a report with the Federal Trade Commission and your local police.

In the following days, you’ll need to change all passwords, review your credit reports, consider a credit freeze, and document everything. While this process can be overwhelming – and extremely cumbersome – taking quick action can significantly limit the damage.

Staying informed about AI scam tactics through reputable cybersecurity resources is essential. Reporting suspected scams to relevant authorities not only protects you, but it also helps safeguard others. A key takeaway is that staying vigilant is critical to defending against these threats.

Awareness helps communities push back against digital threats. More importantly, it’s key to understand how today’s scams aren’t like yesteryear’s.

Recognizing the signs of scams can provide stronger defense during this holiday season. And as you develop your threat identification techniques, don’t forget to share with your family and friends.
