Astronomical Mystery: Giant Alien Planet Orbiting Three Suns
Binary stars are well-known and even trinary systems may be common but most of them are crowded together and thus, difficult to find and study. Additionally, it has long been considered they are inhospitable to planets...

Radio Emission From Ultracool Dwarf Detected By Arecibo Telescope
The Arecibo Telescope in Puerto Rico has discovered sporadic bursts of polarized radio emission from the T6.5 brown J1047+21.
Because Arecibo is a single, fixed-dish telescope, it has a restricted practical sensitivity to weak, quiescent emission from radio sources...

Invader From Another Galaxy
This alien intruder from another galaxy is in many ways different from other exoplanets observed by astronomers.
Located about 2000 light-years from Earth in the southern constellation of Fornax (the Furnace), the Jupiter-like planet orbits a dying star of extragalactic origin and risks to be engulfed by it.

Intimate Connection Between Black Holes And New-Born Stars
Astronomers have known for some time that black holes and supermassive black holes accretion and star formation appear intimately connected.
However, it does not mean that powerful gravitational forces of the black holes disrupt surrounding material in their vicinity.

Power To See Most Distant Objects In The Universe
The 3C294, is one of the most distant galaxies recorded by Chandra, the most sophisticated X-ray observatory ever built. The cluster 3C294 is even 40 percent farther (!) than the next most distant x-ray galaxy cluster. Chandra focus on X-rays from high-energy regions of the Universe and see the invisible. It is so sensitive that it can capture images of particles as they disappear into a black hole deep in outer space.

"Pillars Of Creation" Are Gone
Every time you look at the beautiful and famous image of the Pillars of Creation taken by Hubble back in 1995, you are actually admiring something that no longer exists.
In fact, the Pillars of Creation were already long gone by the time the image was captured!
