Following the titanic mass ejection of a large piece of its visible surface. The escaping material cooled to form a cloud of dust that temporarily made the star look dimmer, as seen from Earth. This unprecedented stellar convulsion disrupted the monster star’s 400-day-long oscillation period that astronomers had measured for more than 200 years. The Read more about Hubble sees supergiant Betelgeuse slowly recovering after blowing its top[…]

A new analysis of seismic data from NASA’s Mars InSight mission has revealed a couple of surprises. The first surprise: the top 300 meters of the subsurface beneath the landing site near the Martian equator contains little or no ice. “We find that Mars’ crust is weak and porous. The sediments are not well-cemented. And Read more about Subsurface water on Mars defy expectations: Physics connects seismic data to properties of rocks and sediments[…]

Australian media has reported that space debris found in New South Wales was indeed junk from a SpaceX mission, including one piece measuring nearly three meters in length. The black shard, found sticking out of the ground, is presumed to be Elon Musk’s take on 2001’s Monolith. The Register asked SpaceX to clarify, but we Read more about SpaceX shows that it too can shower the Earth with debris[…]

As more private astronauts venture out into space, NASA is seeking to better regulate their journeys to Earth orbit. The space agency recently announced some updates to the set of rules required for upcoming private astronaut missions, including the stipulation that all future missions be led by a former NASA astronaut. NASA released the list Read more about NASA Is Changing Its Rules for Private Astronauts[…]

Scientists believe we’ve only discovered about 5% of the universe. Here’s a map of what we’ve found so far, visualized using a log scale. Source: A Logarithmic Map of the Entire Observable Universe

China is claiming that as of Wednesday, its Tianwen-1 Mars orbiter has officially photographed the entire Red Planet. And it’s shown off new photos of the southern polar cap and a volcano to prove it. “It has acquired the medium-resolution image data covering the whole globe of Mars, with all of its scientific payloads realizing Read more about China has photographed all of Mars from orbit[…]

South Korea conducted its first successful satellite launch using a domestically developed rocket on Tuesday, officials said, boosting its growing aerospace ambitions and demonstrating it has key technologies needed to launch spy satellites and build larger missiles amid tensions with rival North Korea. The three-stage Nuri rocket placed a functioning “performance verification” satellite at a Read more about South Korea Launches First Satellite With Homegrown Rocket[…]

This evening, Boeing’s new passenger spacecraft, the CST-100 Starliner, successfully docked itself to the International Space Station — demonstrating that the vehicle can potentially bring humans to the ISS in the future. It’s a crucial capability that Starliner has finally validated in space after years of delays and failures. Starliner is in the midst of Read more about Boeing’s Starliner successfully docks to the International Space Station for the first time[…]

[…] an international team of astronomers, including a team that I led from the University of Central Lancashire, has unveiled the first image of the object lurking at the centre of the Milky Way – and it is a supermassive black hole. This means there is now overwhelming evidence for the black hole, dubbed Sagittarius Read more about How we captured first image of the supermassive black hole at centre of the Milky Way[…]

The researchers observed unexpected, rapid “electron precipitation” from low-Earth orbit using the ELFIN mission, a pair of tiny satellites built and operated on the UCLA campus by undergraduate and graduate students guided by a small team of staff mentors. By combining the ELFIN data with more distant observations from NASA’s THEMIS spacecraft, the scientists determined Read more about Researchers discover source of super-fast electron rain[…]

On Feb. 3, SpaceX launched 49 small satellites into low earth orbit as a part of its Starlink program, an advanced satellite internet service that, as with many other products and services pioneered by American billionaire Elon Musk, is at least a little controversial. The satellites were carried into the atmosphere without a problem and Read more about Solar Storm Destroys 40 New SpaceX Starlink Satellites[…]

Chinese satellite was observed grabbing another satellite and pulling it out of its normal geosynchronous orbit and into a “super-graveyard drift orbit.” The maneuver raises questions about the potential applications of these types of satellites designed to maneuver close to other satellites for inspection or manipulation and adds to growing concerns about China’s space program Read more about A Chinese Satellite Just Grappled Another And Pulled It Out Of Orbit[…]

Just over 1,500 light-years away in the constellation of Hercules there’s a rugby ball-shaped exoplanet orbiting a star. It’s the first time astronomers have been able to detect such an unusual shape of an alien world. Most planets are more or less spherical due to gravitational forces that pull matter equally in from all sides, Read more about Massive rugby ball-shaped exoplanet spotted 1,500 ly away[…]

In a study published today in Nature, they describe an amorphous, 1,000-light-year-wide bubble ensconcing Earth that is responsible for those stars. Called the Local Bubble, the researchers believe it formed from a series of large explosions that blasted energy into space over the last 14 million years. Those explosions were supernovae—spectacular collapses of stars that Read more about Earth Is in a 1,000-Light-Year-Wide Bubble That Cooks Up Stars[…]

Heads up, future space travelers: No more commercial astronaut wings will be awarded from the Federal Aviation Administration after this year. The FAA said Friday it’s clipping its astronaut wings because too many people are now launching into space and it’s getting out of the astronaut designation business entirely. The news comes one day ahead Read more about FAA: No more commercial astronaut wings, too many launching. You still get to be on a list.[…]

Astrophysicists believe the heliosphere protects the planets within our solar system from powerful radiation emanating from supernovas, the final explosions of dying stars throughout the universe. They believe the heliosphere extends far beyond our solar system, but despite the massive buffer against cosmic radiation that the heliosphere provides Earth’s life-forms, no one really knows the Read more about Studying our solar system’s protective bubble[…]

The ranks of orbit-capable spaceflight companies just grew ever so slightly. TechCrunch reports Astra has reached orbit for the first time when its Rocket 3 booster launched shortly after 1AM Eastern today (November 20th). The startup put a mass simulator into a 310-mile-high orbit as part of a demonstration for the US Air Force’s Rapid Read more about Launch startup Astra reaches orbit for the first time[…]

[…] South Australian company Neumann Space has developed an “in-space electric propulsion system” that can be used in low Earth orbit to extend the missions of spacecraft, move satellites, or de-orbit them. Now Neumann is working on a plan with three other companies to turn space junk into fuel for that propulsion system. Japanese start-up Read more about ‘Gas station in space’: new plan to make rocket fuel from junk in Earth’s orbit[…]

In a test of its missile technology, Russia destroyed an old space satellite on Monday, littering Earth’s orbit with fragments and forcing astronauts on the International Space Station to temporarily take shelter. The cloud of debris was generated when Cosmos 1408, a 2,200-kg defunct signals intelligence satellite launched in 1982, was blown up by a Read more about ISS crew shelters from debris after Russia blows up old sat – US angry[…]

A U.S. space launch start-up has, for the first time, demonstrated a kinetic-based system that’s intended one day to put small spacecraft into orbit. The SpinLaunch concept, which feels ripped right from the classic age of science fiction, is based around a vacuum-sealed centrifuge that spins an unpowered projectile at several times the speed of Read more about Space Launch Start-Up Spinlaunch Just Used A Giant Centrifuge To Fling A Projectile Into The Upper Atmosphere[…]

this report from the New York Times about a “particularly unusual” star about 150 light-years away that’s orbited by three planets: What’s unusual is the inclinations of the outer two planets, HD 3167 c and d. Whereas in our solar system all the planets orbit in the same flat plane around the sun, these two Read more about Star System With Right-Angled Planets Surprises Astronomers[…]
