Our solar system might have been a vastly different place before Jupiter arrived, according to a new Proceedings of the National Academy of Sciences that suggests that the gas giant may have destroyed an entire generation of inner planets before entering its current orbit.
A rare class of so-called “active asteroids” that appear to leave behind a tail of dust and debris similar to that of a comet are travelling so fast that they are essentially making themselves blow up, according to research published Friday in Astrophysical Journal Letters.
Want to get a celestial event or object named after you? Here's how and where to report your amateur findings.
A mysterious explosion in the sky observed in the 17th century was not a nova, but a much rarer, violent stellar collision.
Last week, the Mars One “mission” stirred up a bit of a public relations battle. First, Dr. Joseph Roche, an astrophysics professor at Trinity College in Dublin and one of the Mars One 100 "finalists", revealed through an interview with the website Matter that the whole thing just might be a scam. Then, another finalist – Ryan MacDonald, a physics student at Oxford University – posted an online video hitting back at Roche’s claim.
Pluto is finally getting some recognition as New Horizons plans to reach it this summer. But what's next for the spacecraft?
Let’s consider what it would actually take to destroy a planet with a ‘pew pew’ style laser beam, and what kinds of energy would need to be harnessed in a fully armed and operational battle station.
Good news! Experts have analyzed thousands of exoplanets in our galaxy and the calculations show that billions of those stars could have planets in the habitable zone.
WASHINGTON, March 19, 2015 /PRNewswire-USNewswire/ -- Using NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA), an international scientific team discovered that supernovae are capable
Astronomers have identified a previously invisible stellar cluster currently forming over 1 million new stars, according to a report in the journal Nature.
Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...
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...
Ad Astra is a quarterly-published journal of the National Space Society (NSS). The name “ad astra” means “to the stars.” The journal was established following the merger of the L5 Society and the National Space Institute, which formed the NSS in 1987. The NSS is a non-profit aerospace advocacy and educational institution based in Washington DC. On November 28, 2007, the NSS announced MM Publishing Inc. as the newest publisher of Ad Astra. MM Publishing officially took on the role...
Columbia launched from Kennedy Space Center on October 22, 1992 at 1:09 PM EDT and landed at Kennedy on November 1 at 9:05 AM EST. The shuttle orbited 159 times at an altitude of 163 nautical miles at an inclination of 28.45 degrees and travelled 4.1 million miles. The mission lasted 9 days, 20 hours, 56 minutes, and 13 seconds. The mission launched several satellites for international partners. The primary mission objectives were the deployment of the Laser Geodynamic Satellite II...
