While some astronomers are looking for the existence of planets light years away from Earth, a team of Spanish researchers has suggested there could be at least two planets that have yet to be discovered in our very own Solar System.

In four billion years, a mere blink of an eye by universal standards, planet Earth will be part of a galactic collision when our Milky Way will smash into the Andromeda spiral galaxy. Scientists got a preview of that event earlier this week.

Rather than being planetary building blocks, asteroids and meteorites may actually be the byproducts of planetary collisions occurring billions of years ago, according to researchers from MIT and Purdue University.

Detailed analysis of different stellar populations in the disk of Andromeda suggests the galaxy may have had a far more violent history of mergers with smaller galaxies than the Milky Way, researchers from the University of California, Santa Cruz report in a new study.

Something seems to be missing in a new image captured by the European Southern Observatory (ESO) this week – there’s a large patch of darkness where there should be stars.

The stage has been set for a explosion of apocalyptic proportions, as two distant supermassive black holes just one light-year apart are on a collision course that could result in the destruction of their home galaxy and release as much energy as 100 million supernovas.

Saturn Cassini

Scientists have paired NASA's Cassini spacecraft with the National Science Foundation's Very Long Baseline Array (VLBA) radio-telescope system to pinpoint the position of Saturn and its family of moons to within about 2 miles (4 kilometers).

A titanic eruption took that took place at least two million years ago forced gases and other materials outward at speeds of up to two million miles per hour, and astronomers are just now witnessing the aftermath of the explosion thanks to NASA’s Hubble Space Telescope.

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...

Tropic of Capricorn
2013-02-21 13:31:57

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...
