Study Explains Blinking Gamma-Ray Bursts Using Falling Stardust, Unsteady Jets
Astrophysicists have developed the first 3D simulation of the entire evolution of a jet from its birth by a rotating black hole to its emission far from the collapsing star. Simulation explains that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the ...

Astronomers May Have Discovered a Black Hole Candidate Through Gravitational Microlensing
A team of astronomers from the University of California, Berkeley, has discovered what appears to be a free-floating black hole for the first time using gravitational microlensing. The unseen compact object's mass is estimated to be between 1.6 and 4.4 times that of the Sun, according to the astronomers.

Closest 'Potentially Habitable' Planet Found 14 Light Years Away
Astronomers have discovered the closest potentially habitable planet found outside our solar system, orbiting a star just 14 light years away.

These Baby 'Monster' Galaxies Are Swaddled in Dark Matter
Scientists have discovered a nursery full of monstrous cosmic babies. In a study published Friday in the Astrophysical Journal Letters, researchers report nine so-called monster galaxies - ones bursting with rampant star formation - from the early days of the solar system.

Sun Can Produce 'Superflares' That May Disrupt Life on Earth
Sun has the potential to produce superflares, with energy equivalent to a billion megaton bombs, which may severely disrupt power grids and communication systems on the Earth, a new study has found.
