We’re closing out our #BlackHoleFriday with a black hole that’s close to home, on a cosmic scale. At the center of our own Milky Way galaxy lies a supermassive black hole named Sagittarius A*. Located about 26,000 light years from Earth, this black hole contains around 4.5 million times the mass of our Sun!
Once a controversial claim, this astounding conclusion is now virtually inescapable and based on observations of stars orbiting very near the galactic center. Astronomers patiently followed the orbit of a particular star. Their results showed that the star was moving under the influence of the enormous gravity of an unseen object which must be extremely compact, and contain huge amounts of matter – a supermassive black hole.
This Chandra X-ray telescope image shows the X-ray light from a region of space a few light years across. The black hole is invisible, but is near the center of this image. The gas near the center produces X-ray light as it is heated. Many of the ‘stars’ in the field probably have much smaller black holes near them that are producing the X-ray light from the gas they are consuming.
Thanks for joining us for our 5th annual #BlackHoleFriday!

A few silly shenanigans with this little girl before dinner.
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

Spacecraft come in all shapes and sizes! Our Low-Density Supersonic Decelerator (LDSD) test vehicle is shaped like disk, and is used to test techniques for entering Mars’ atmosphere.
==========
¡Las naves espaciales tienen distintas formas y tamaños! Nuestro vehículo experimental, LDSD tiene forma de disco y es utilizado para probar técnicas de ingreso a la atmósfera de Marte.
