This supermassive black hole feeds on frigid gas

The BCG is a giant elliptical galaxy, tens of thousand light years across, with a supermassive black hole at its core.Streaking toward the Brightest Cluster black hole are three enormous, lumpy clouds of cold gas, and they’re all raining into the black hole at the same time.

The ‘alien megastructure’ star continues to defy explanation The star KIC 8462852 sits 1,480 light years away in the constellation Cygnus.It wasn’t a planet, and some speculated that what we were seeing was evidence of a massive alien megastructure.

Astronomers discover a ‘starving’ supermassive black hole at the center of a galaxy

Astronomers discover a ‘starving’ supermassive black hole at the center of a galaxy What happens when a black hole falls on hard times?An international team of astronomers have found a black hole that’s rapidly getting dimmer, and they think it’s starving.

Astronomers discover true nature of ‘giant space blob’

Astronomers discover true nature of ‘giant space blob’ We’ve been staring at the first such blob, called Lyman-Alpha blob 1 or LAB-1 for short, since we found it in 2000.The birth of galaxies is not a peaceful process, and these young galaxies could be bombarding the star nurseries with high-energy matter, driving star formation.

NASA-funded science rocket discovers mysterious X-ray emissions in space

NASA-funded science rocket discovers mysterious X-ray emissions in space A sounding rocket (also called a research rocket) is a rocket designed to take measurements and perform experiments in sub-orbital flights.On this run, the instrument solved a longstanding question about the origins of the dim X-ray fog blanketing the entire sky.

Astronomers get a chance to watch a rare red nova in its opening strains

Astronomers get a chance to watch a rare red nova in its opening strains As you might suspect, a contact binary is an unstable state of affairs.When that finally happens, the cores of the two stars will merge and then explode as a luminous red nova.

The 25 best Hubble Space Telescope images

The 25 best Hubble Space Telescope images The Hubble Space Telescope has been silently hovering above Earth for over 25 years, but it’s still returning spectacular images of the cosmos.Most of the famous Hubble images were taken with the Wide Field and Planetary Camera 2 (WFPC2), and the Wide Field Camera 3 (WFC3).
