NuSTAR finds Cosmic Clumpy Doughnut around Black Hole

The most massive black holes in the universe are often encircled by thick, doughnut-shaped disks of gas and dust. This deep-space doughnut material ultimately feeds and nourishes the growing black holes tucked inside. Until recently, telescopes weren’t able to penetrate some of these doughnuts,ie tori.

“Originally, we thought that some black holes were hidden behind walls or screens of material that could not be seen through,” said Andrea Marinucci of the Roma Tre University in Italy...

Hubble Sees the Force Awakening in a Newborn Star

Just in time for the release of the movie “Star Wars Episode VII: The Force Awakens,” NASA’s Hubble Space Telescope has photographed what looks like a cosmic, double-bladed lightsaber. In the center of the image, partially obscured by a dark, Jedi-like cloak of dust, a newborn star shoots twin jets out into space as a sort of birth announcement to the universe. It does not lie in a galaxy far, far away, but inside our Milky Way. It’s inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex,1,350 light-years away.

When stars form within giant clouds of cool molecular hydrogen, some of the surrounding material collapses under gravity to form a rotating, flattened disk encircling the newborn star...

Nearby Star Hosts Closest Alien Planet in the ‘Habitable Zone’

This is a simulation of the orbital configuration of the Wolf 1061 system. Wolf 1061 is an inactive red dwarf star, smaller and cooler than our sun, 14 light years away. The orbits for the planets b, c and d (ordered from the inner planet to the outer) have periods of 4.9 days, 17.9 days and 67.2 days. In the simulation we show the planet orbits as all lying in a single plane. The planetary habitable zone around the star is marked in green -- the colors grade from red (where a planet would be too hot), through green (where the surface of a planet could sustain liquid water), through to blue (where a planet would be too cold).

Monster Planet is ‘Dancing with the Stars’

A team of scientists has discovered a highly unusual planetary system comprised of a sun-like star, a dwarf star, and an enormous planet "dancing" in between. The dwarf star and the planet have been gravitationally influencing each other for millions of years. Specifically, the planet's eccentricity (the amount it deviates from being perfectly circular) and orbital inclination, meaning its angle relative to the equatorial plane of the primary star, have been oscillating back and forth in a process known as Kozai oscillations -- and will continue to do so for the foreseeable future.
