Today Chandra is studying a galaxy in the constellation Canes Venatici (Latin for 'hunting dogs'). Nearby in the sky is M63, also known as the Sunflower Galaxy. Similar in size to our own Milky Way Galaxy, this celestial bloom contains over 400 billion stars! 🌻✨

As #BlackHoleWeek closes, here's the most distant supermassive black hole ever detected in X-rays.

Webb revealed the black hole's host galaxy existed 470 million years after the big bang, while Chandra Observatory confirmed the existence of the black hole: go.nasa.gov/4bzilwe

The Event Horizon 'Scope released the first direct image of a black hole in galaxy M87. DYK that coordinated observations with 19 of the world's most powerful telescopes, including NASA's Chandra, have also collected light from M87 across the electromagnetic spectrum? #BlackHoleWeek ⚫

Ever wonder what happens when you fall into a black hole?

Thanks to a new, immersive visualization produced on a NASA supercomputer, we're kicking off #BlackHoleWeek with a virtual plunge into the event horizon—a black hole's point of no return: go.nasa.gov/44MCBs5

Starting on Monday, get pulled into a whole week of content about some of our favorite — and most mysterious — cosmic objects.

How will you celebrate? #BlackHoleWeek

This timelapse from NASA's Chandra Observatory features data from 2000 through 2019 of Cassiopeia A - the remains of a supernova estimated to have exploded about 340 years ago in Earth’s sky.

Watch the debris field from the supernova remnant, including its blast wave, expanding! 🌟

On a scale of 1-10, rate the Cartwheel galaxy’s neat trick! Hubble, @ChandraXray, GALEX, and Spitzer captured it in multiple types of light, revealing ripples of star formation from a collision with a smaller galaxy. go.nasa.gov/3JFmjHG #NationalCartwheelDay

New timelapses of two of the most famous objects in the sky — the Crab Nebula & Cassiopeia A! X-ray data collected by Chandra over about two decades shows dramatic changes in the debris & radiation remaining after the explosion of two massive stars. More: s.si.edu/timelapse24

When seen through a small telescope, this nebula's gleaming-white central star overwhelms the view. However, by averting your gaze a bit, the nebula's dust clouds come into view. This optical trickery earned NGC 6828 the nickname the 'Blinking Planetary.' What would you call it?

Chandra can observe Earth's X-rays too! In fact, Chandra observed the Earth 10 times over a four-month period in 2004. Some of the X-rays Chandra observed, which have been superimposed on a simulated images of the Earth, are seen here at four different epochs. #EarthDay

Today Chandra is studying NGC 2440, a dying star that's providing a spectacular final performance. The white dwarf star at the heart of this planetary nebula is one of the hottest known, with a surface temperature of nearly 222,000 degrees Celsius (400,000 degrees Fahrenheit).

Oops I did it again 🤭

#TotalSolarEclipse

Can't go outside and watch the #eclipse today? Watch it online through the eyes of NASA! Live coverage starts at 1pm EDT: go.nasa.gov/Eclipse2024Live

Can't watch online either? Here's a bright, beautiful orb just for you. Planetary nebula IC 418, about 3,900 light-years away.
