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.

NASA’s Chandra Sees Surprisingly Strong Black Hole Jet at Cosmic “Noon”

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA’s Chandra X-ray Observatory and discussed in our latest press release. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the big bang itself. Astronomers used […]

How Big is Space? We Asked a NASA Expert: Episode: 61

How big is space? Space is really big. Thinking about our solar system, let’s imagine you could get in a car and drive to Pluto at highway speeds. It would take you about 6,000 years to get there. When we start to think about other stars outside of our solar system, we need to think […]
