The "Cloaked" Star Was Difficult To Find
An object obscured by dust, and buried in a two-star system enshrouded by dense gas, is not easy to find.
A "cloaked" star was discovered after it ate a little of its neighbor. The meal must have given the star a bit of indigestion, because it "burped" with a blast of high-energy radiation, which gave it away.

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.

"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!
