Latest Astronomy Stories
We may not yet be able to assume that intelligent-life exists on other planets, but a team of Australian scientists are confident there are plenty of planets within our galaxy capable of supporting it--hundreds of billions of “Earth-like” planets, in fact.
WASHINGTON, Feb. 4, 2015 /PRNewswire-USNewswire/ -- NASA's New Horizons spacecraft returned its first new images of Pluto on Wednesday, as the probe closes in on the dwarf planet.
Astronomers have discovered that the old Whirlpool Galaxy has some fancy new plumes.
Interstellar gas is the lifeblood of a galaxy, and when it runs out of gas, the galaxy becomes a dead remnant of its former self. (That's also how we feel after eating Thai.)
LA JOLLA, Calif., Feb. 2, 2015 /PRNewswire/ -- Regulus Therapeutics Inc.
Reports published last year claiming to have detected evidence of gravitational waves emitted immediately following the Big Bang were inaccurate, new analysis of the data has revealed.
ESO's Very Large Telescope (that's its actual name) in Chile has taken a new image of the faint cometary nebula CG4. This new image depicts the head of the nebula and resembles a menacing beast's mouth.
Planets capable of supporting life could start out as gaseous worlds similar to Neptune, only to be transformed by the combination of two phenomena that individually can inhibit their potential habitability, University of Washington astronomers have discovered in a new study.
Watch out Saturn, there's a new star in town. A huge star has been discovered with rings 200 times bigger and brighter than Saturn's, and a recent eclipse allowed for scientists to gather more intel on this galactic super star.
Astronomers have discovered the oldest known planetary system ever – a star that is more than 11 billion years old and orbited by at least five rocky planets that are all smaller than Earth.
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...
