NASA’s Swift Sees ‘Wandering’ Mega Black Hole Shredding Star

NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a faraway galaxy. These phenomena are rare to begin with, and none had ever before been seen so far outside of a galaxy’s core. “We were looking for these star-shredding events as a way […]

NASA’s Roman Telescope Will Spot Distant Black Holes That Shred Stars

Lee esta nota de prensa en español aquí. How do black holes at the center of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances, which existed much earlier in the universe’s history. New research suggests NASA’s Nancy Grace Roman Space Telescope, which […]

NASA’s Chandra Reveals ‘Red, White, Blue’ Universe for US 250th

In celebration of the 250th birthday of the United States, NASA has unveiled four cosmic images from its Chandra X-ray Observatory rendered in red, white, and blue that represent the wonders of the universe the agency explores. The images are accompanied by a trio of new sonifications – a technique that translates astronomical data into […]

NASA Connects Little Red Dots with Chandra, Webb

A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]

NASA Finds Young Stars Dim in X-rays Surprisingly Quickly

Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal.

NASA’s Chandra Finds Black Hole With Tremendous Growth

A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA’s Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the big bang. The black hole weighs about a billion times the mass of the […]

One Survey by NASA’s Roman Could Unveil 100,000 Cosmic Explosions

Scientists predict one of the major surveys by NASA’s upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence of some of the universe’s first stars, which are thought to completely self-destruct without leaving any remnant behind.

3 Years of Science: 10 Cosmic Surprises from NASA’s Webb Telescope

Since July 2022, NASA’s James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and analyze otherwise invisible infrared light, Webb is making observations that were once impossible, changing our view of the cosmos from the most distant galaxies to our own solar system.

NASA’s Roman to Peer Into Cosmic ‘Lenses’ to Better Define Dark Matter

A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos.
