JWST uncovers the universe’s farthest dormant black hole, 6 billion solar masses

The James Webb Space Telescope identified the most distant dormant black hole in a galaxy more than 10 billion light-years away (MRG-M0138), with a mass of about six billion solar masses. Because the black hole is not accreting, it’s invisible across wavelengths; researchers measured its mass by tracking the motions of stars around it, aided by gravitational lensing that magnified the system. The finding helps illuminate black hole growth in the early universe and how such black holes influence galaxy evolution, with future surveys like Euclid and the Roman Space Telescope expected to find more of these objects.

Earthshine Moment: Christina Koch Captures Earth from Artemis II Orion Flight

NASA posted a video captured by Artemis II astronaut Christina Koch showing Earthshine—sunlight reflecting off Earth—from about 33,800 miles away on the Orion spacecraft during the 10-day lunar flyby; Koch’s footage comes as the Artemis II crew (Reid Wiseman, Victor Glover, Jeremy Hansen, Koch) traveled farther from Earth than any humans in history, surpassing Apollo 13, and the clip was released around Earth Day.

Night-Sky Brightening: 4,000 Orbital Mirrors Target Earth Illumination in 2026

Night-Sky Brightening: 4,000 Orbital Mirrors Target Earth Illumination in 2026

A California startup, Reflect Orbital, plans to deploy about 4,000 55-meter-wide mirrors in low Earth orbit to reflect sunlight back to Earth at night, with Earendil-1 launching in April 2026 to illuminate nighttime solar-power sites and other critical areas. The project has sparked backlash from astronomers, environmentalists, and sleep researchers due to potential sky brightness and telescope interference, as well as concerns about wildlife disruption and governance since private entities would control illumination. Simulations suggest beams could be bright enough to affect observations, and atmospheric scattering could spread light beyond the target zone, raising questions about data loss and fairness across borders.**

"SpaceX Dragon Capsule Debris Crashes in North Carolina Mountains"

A piece of space debris from SpaceX's Crew-7 Dragon capsule was discovered near Canton, North Carolina, by a groundskeeper at a luxury camping site. The debris, likely from the spacecraft's "trunk" section, was identified by astrophysicist Jonathan McDowell. This incident highlights the occasional survival of large spacecraft components after reentry. Despite the rarity of such events, the Glamping Collective plans to display the debris as a unique find.

"Urgent Call: Protecting Earth from Space Pathogens"

NASA is responding to the Mars Sample Return Independent Review Board's report and outlining the next steps for the program. The Bipartisan Commission on Biodefense, led by former Democratic Congresswoman Donna Shalala and former Republican Congresswoman Susan Brooks, is calling for measures to defend Earth from potential space bugs that could be brought back from Mars or exist in space. They emphasize the need for coordination, collaboration, and investment in research and technology to prevent the contamination of extraterrestrial environments and protect Earth's inhabitants from potential space-related biological threats.

"NASA Confirms Space Station Debris Hit Florida Home"

NASA has confirmed that the object that fell into a Florida home last month was part of a battery pack released from the International Space Station, sparking legal discussions about who should pay for the damages. The cylindrical piece of metal tore through the homeowner's roof, but luckily, no one was hurt. The homeowner, Alejandro Otero, had suspected the object came from space even before NASA's confirmation. NASA retrieved the object and confirmed its origin, and now legal codes and intergovernmental agreements are being navigated to address the situation.

"NASA's Rare Repair Spacewalk: Fixing Busted Telescope"

NASA is planning a rare spacewalk to repair a telescope mounted on the International Space Station that has been affected by unwanted sunlight leaking into its sensitive detectors. The repair involves installing patches to block out the sunlight, and the astronauts will carry out the repair during an upcoming mission. This challenging repair task is necessary to ensure the telescope's normal operations and measurements are not affected by the light leak.

"Astronauts to Conduct Rare Repair Spacewalk on Leaky ISS Telescope"

NASA plans to send astronauts to repair the Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station (ISS) due to a "light leak" issue affecting its X-ray measurements. The telescope, launched in 2017, was not designed for servicing, presenting a challenge for the repair. This will be the fourth science observatory that NASA has risked astronauts to repair, highlighting the risks and rewards of having astronauts fix equipment not originally intended for servicing in space.

"NASA Confirms Space Junk from ISS Crashes Through Florida Home"

NASA confirmed that the object that crashed through a Florida home's roof in March was debris from the International Space Station, specifically a piece of a cargo pallet of depleted batteries jettisoned in 2021. The 1.6-pound debris, identified as a stanchion from NASA flight support equipment, survived re-entry and impacted the home. NASA will investigate the cause of the debris survival and update modeling and analysis as needed.

"Space Junk from International Space Station Crashes into Florida Homes"

Nasa has confirmed that a heavy metal chunk that crashed into a Florida home was space junk from a cargo pallet released from the international space station in 2021. The debris, weighing 1.6lb and measuring about 4in by 1.6in, was supposed to be destroyed in Earth's atmosphere but instead crashed through a Florida home. Nasa will investigate how the debris survived re-entry and "update modeling and analysis," but it's unclear if they will cover the cost of damages to the homeowner's property.

"NASA Confirms Space Station Debris Crashes into Florida Home"

NASA confirmed that a space object that crashed through a home in Naples, Florida was a stanchion from a cargo pallet containing aging nickel hydride batteries from the International Space Station. The object, made of the metal alloy Inconel, survived re-entry through Earth’s atmosphere and impacted the home, causing significant damage. NASA is analyzing the object to determine its origin and remains committed to responsibly operating in low Earth orbit.

"NASA Confirms Space Station Debris Crashes into Florida Home"

NASA confirmed that the metal object that crashed through a Florida home was part of a pallet of space station junk released into space in 2021. The debris, which was expected to burn up upon reentry, instead survived and struck the home, sparking curiosity and prompting NASA to investigate. The homeowner, Alejandro Otero, is in contact with his insurance company about repairs, and it remains unclear whether NASA will cover the costs. The incident has raised questions about liability for space debris damage and highlighted the need to address the potential risks posed by space debris as human activity in space continues to increase.

"NASA Confirms Space Station Debris Struck Florida Home"

NASA confirmed that a piece of space debris that pierced a Florida man's roof was a stanchion from equipment used to mount batteries onto the International Space Station's cargo pallet, which was jettisoned three years ago. The 1.6 lb, 4-inch tall object missed the homeowner's son and caused significant damage. NASA will investigate why the debris did not disintegrate as expected during atmospheric re-entry, highlighting the safety risks posed by space junk to people and property on Earth.
