Imagine how brightly our Sun shines on a warm summer day. Now, try to imagine a star approximately 10 million times brighter. A team of astronomers have discovered such a pulsating star.
The same phenomenon that causes a bumpy airplane ride, turbulence, may be the solution to a long-standing mystery about stars' birth, or the absence of it, according to a new study using data from NASA's Chandra X-ray Observatory.
Astronomers captured pictures not only of Thursday's partial solar eclipse, but also of the "monster" sized active region or sun spot that has many comparing it to one of a similar size that occurred 11 years ago.
The moon passed between the Earth and the sun on Thursday, Oct. 23. While avid stargazers in North America looked up to watch the spectacle, the best vantage point was several hundred miles above the North Pole.
Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe.
As seen in the Academy Award-winning film Gravity, debris in orbit around Earth is a serious hazard for astronauts and spacecraft operating high above our planet.
Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.
It might look like a spoked wheel or even a "Chakram" weapon wielded by warriors like "Xena," from the fictional TV show, but this ringed galaxy is actually a vast place of stellar life.
After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Beta Pictoris is a young star located about 63 light-years from the Sun. It is only about 20 million years old and is surrounded by a huge disc of material — a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids.
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...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
