@Lightspacestar2 @NASAHubble @almaobs Happy Valentine's Day!🥰

Today Chandra is observing a cluster of galaxies called Abell 1795. Back in 2005, Chandra caught a bright, long duration flare in one of the cluster's galaxies. It was the first time humans observed a black hole destroying a star in a dwarf galaxy.⚫

The most massive black holes in the universe might be able to cook for themselves! A new survey of galaxy clusters provides evidence that outbursts from black holes can help black holes feed themselves. More about the discovery:

@NASAHubble There's nothing like a good view of the Crab Nebula in the morning! Remember the last time we saw it together along with NASA's IXPE mission?⬇️ Good times!🤩

The finite speed of light means that we must always be out of date, no matter how hard we strive to keep up with the times. Thus, the seemingly simple question — what is happening right now on the Sun? — cannot be answered by an observer on Earth, because it takes light 8 minutes to reach Earth from the Sun. For distant objects, the light travel times are even longer, so our information about the galaxy cluster Abell 370, which is 4 billion light-years away, is 4 billion years out of date! The time in the past at which the light we now receive from a distant object was emitted is called the look-back time. When astronomers discuss events in distant objects, they take for granted that the actual event occurred earlier because of light travel time. It is similar to finding a series of photographs of a child in a 300 year-old time capsule. We could see how the child was developing 300 years ago, even though the child would no longer be alive.

@rebeljubilee @NASAHubble The blue haze represents multimillion-degree gas detected by NASA's Chandra in X-ray light.

Which planets outside our solar system might be able to sustain life as we know it?🪐 A new study examines the effects of extreme space weather on potential planets around the most common type of stars. More about the discovery at: #AAS245

One of the most extreme environments in our galaxy is the region around our galaxy's supermassive black hole, Sagittarius A*. Using decades of data, scientists have created the first 3D maps of star-forming gas clouds nearby: #AAS245

Video description: Wispy green clouds in a conical shape strongly resemble an evergreen tree. Tiny specks of white, blue, purple, and red light, stars within the cluster, blink throughout the structure, turning the cloud into a festive, cosmic Christmas tree!
