NASA frequently shares fascinating insights about space on social media. Their posts never fail to amaze us, whether it's about distant galaxies or images of beautiful constellations. If you're someone who's interested in all things space-related, we've got you covered with his three notable celestial discoveries made by space agencies.

1.Z 229-15
The object, captured by the Hubble Space Telescope, is about 390 million light-years from Earth. According to NASA, Z 229-15 is “sometimes an active galactic nucleus (AGN), sometimes a quasar, and sometimes a Seyfert galaxy.”
AGNs are small regions that are much brighter than the stars in the galaxy and are located at the center of some galaxies. Quasars are a type of AGN that are incredibly bright and far from Earth. Seyfert galaxies are active galaxies with bright AGNs.
2. Brown dwarf
According to NASA, “brown dwarfs are objects that straddle the star-planet boundary. They form like stars and grow so dense that they collapse under gravity, but they grow so densely that they begin to fuse with hydrogen and turn into stars. It doesn't get too dense and hot' stars. ” Some brown dwarfs can rival giant planets. (Also read: 5 fascinating nostalgic photos of NASA's Earth, a timeless wonder)
3. Cosmic Hand
NASA's two X-ray telescopes, Chandra and IXPE, have taken photos of the “bones” of a cosmic “hand” that died 1,500 years ago. It is actually an Appulsar-like nebula shaped like a human hand. This pulsar is 16,000 light-years from Earth and can be found at the base of the nebula's “palm”. Astronomers will use the acquired X-ray data to learn more about how such objects form.
