A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can escape. The event horizon isn’t a surface like Earth’s or even the Sun’s.NASA Universe Exploration
Next up for #BlackHoleWeek, meet NGC 4395!
About 14 million light-years away, this spiral galaxy contains an active galactic nucleus (AGN) powered by a supermassive black hole.

The galactic nucleus in NGC 4395 has a comparably low luminosity to other AGNs and its black hole is about 10,000 times the mass of our Sun!
This new Hubble image of NGC 4395 captures one of the galaxy's spiral arms.

Most galaxies, like our Milky Way, have black holes at their centers. This computer-simulated image shows what that might look like. In the center is the black hole’s event horizon, where no light can escape.

Webb's on the case 🔎
Webb found hints of water vapor while studying rocky exoplanet GJ 486 b. Scientists are puzzled whether this could be due to spots on its star, or if this could indicate the 1st atmosphere definitively detected around a rocky world: go.nasa.gov/41K2Ahj

Welcome to #BlackHoleWeek!
To celebrate, Hubble has new images to share featuring active galactic nuclei, or AGNs. Some galaxies contain AGNs, which are extremely bright central regions that host a supermassive black hole!
First up, feast your eyes on NGC 3489 ⬇️
#Hubble
NGC 3489 is home to a huge black hole. The luminous center is caused when the black hole devours material that gets too close to it!
This galaxy resides about 30 million light-years away: go.nasa.gov/429QWMs
Stay tuned for more new images of AGNs this week!

Tale as old as time. ☄️
Unusual asteroid Phaethon behaves like a comet. It brightens and forms a tail as it nears the Sun and is the source of a meteor shower, something usually led by comets. But this asteroid's tail tells a different story:
