Hubble Finds Best Evidence for Elusive Mid-Sized Black Hole

From NASA March 31, 2020 Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as “intermediate-mass,” which betrayed its existence by tearing apart a wayward star that passed too close. Weighing in at about 50,000 times the mass of our Sun, the black…

Chandra Data Tests ‘Theory of Everything’

March 19, 2020 One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a “theory of everything” that would tie together our understanding of the physical universe. Despite having many different versions of string…

Hubble’s Close-Up of Spiral’s Disk, Bulge

From NASA Dec. 20, 2019 This image from the NASA/ESA Hubble Space Telescope shows IC 2051, a galaxy in the southern constellation of Mensa (the Table Mountain) lying about 85 million light-years away. It is a spiral galaxy, as evidenced by its characteristic whirling, pinwheeling arms, and it has a bar of stars slicing through…

Black Hole Nurtures Baby Stars a Million Light-Years Away

From NASA Nov. 29, 2019 Black Hole Nurtures Baby Stars a Million Light-Years Away Back to Gallery Black holes are famous for ripping objects apart, including stars. But now, astronomers have uncovered a black hole that may have sparked the births of stars over a mind-boggling distance, and across multiple galaxies. If confirmed, this discovery,…

Stars Are Being Born in the Depths of a Black Hole

From NASA Stars Are Being Born in the Depths of a Black Hole Located about 5.8 billion light years from Earth in the Phoenix Constellation, astronomers have confirmed the first example of a galaxy cluster where large numbers of stars are being born at its core. Galaxy clusters are the largest structures in the cosmos…

Hubble Finds Medusa in the Sky

From NASA Oct. 24, 2019 Hubble Finds Medusa in the Sky Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one entity, but two. An early galaxy consumed a smaller gas-rich system, throwing out streams of stars and dust into space. These streams, seen rising from…

Hubble Spots Stunning Spiral Galaxy

From NASA May 3, 2019 Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes — especially when viewed through a telescope such as the…
