Latest Astronomy Stories
You could name a planet after your mom or your cat, or even your favorite TV character.
Researchers have for the first time captured detailed images of heat rising from the horseshoe-shaped lava lake on Io, the innermost moon of Jupiter. Cool!
This new exoplanet appears to be just too big for its star and it’s got the astronomers frantically scratching their heads.
NASA sounding rocket was launched towards a supernova remnant, with the goal of examining the X-rays emitted by the object to determine the composition of this 20,000-year-old explosion’s debris.
These black holes are always hungry and are huge! Constantly gorging yourself on gas 'donuts' can do that to you.
It's confusing, we know. But we have the answer. At least by astronomer standards.
Braaaaaains. A mysterious high-energy X-ray signal detected by NuSTAR could be the sounds of “zombie” stars feeding on the “brains” of nearby stellar companions, according to research published recently in the journal Nature.
For the first time, astronomers have produced a fully 3D view of the Pillars of Creation using the Very Large Telescope to capture the iconic billowing dust pillars in new detail and discover never-before-seen features.

After several years of service studying Mercury, the closest planet to the sun, the NASA MESSENGER spacecraft has run out of fuel and will fall to Mercury’s surface this afternoon, sometime around 3:30pm EDT, officials from the US space agency have confirmed.
The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...
Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...
The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
