The European Space Agency utilized polarized light from the earliest days of the universe to reveal that the first stars were formed 100 million years later than previously believed.
New images captured by the Hubble Space Telescope depict a rare event known as a tri-moon conjunction, in which three of Jupiter’s largest moons are passing across the banded face of the gas-giant at the same time, NASA officials announced on Thursday.
Tomorrow night (February 6, 2015), Jupiter, the largest planet in our solar system, will make its closest encounter to Earth until the year 2019 due to its opposition to the Sun, making it visible in the night’s sky. The planet will be located in front of the constellation Cancer, nearby the star Regulus, the brightest star in constellation Leo.
Here's a list of Southern Hemispheric-specific constellations for your reading pleasure.
Our friends in the Southern Hemisphere can’t see some of our beloved constellations, just like we can’t see some of theirs. Here is a list of hemispheric-specific constellations for your reading/viewing pleasure.
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.)

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.

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...
