mercury magnetic field

Stuart Wolpert, University of California - Los Angeles Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. Measurements from NASA's Messenger spacecraft have revealed that Mercury's magnetic field is approximately three times stronger at its northern hemisphere than its southern one. In the current research,...

J.D. Harrington, NASA Headquarters Observations by NASA's Fermi Gamma-ray Space Telescope of several stellar eruptions, called novae, firmly establish these relatively common outbursts almost always produce gamma rays, the most energetic form of light. "There's a saying that one is a fluke, two is a coincidence, and three is a class, and we're now at four novae and counting with Fermi," said Teddy Cheung, an astrophysicist at the Naval Research Laboratory in Washington, and the lead...

WASHINGTON, July 31, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. http://photos.prnewswire.com/prnvar/20081007/38461LOGO These "lensing" galaxies are so massive that their gravity bends, magnifies, and distorts light from...

protoplanetary discs in a double star
2014-07-31 05:31:40

ESO Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary disks in a double star. The new result also helps to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits. The results will appear in the journal...

redOrbit Staff & Wire Reports - Your Universe Online For the first time, astronomers have been able to precisely measure the mass of the Milky Way, and have discovered that our solar system's home is actually smaller than previously believed. As reported this month in the journal Monthly Notices of the Royal Astronomical Society, researchers from the University of Edinburgh, the University of British Colombia, Carnegie Mellon University and NRC Herzberg Institute of Astrophysics...

Enceladus South Pole
2014-07-29 03:45:31

Preston Dyches/Dwayne Brown/Steve Mullins, NASA Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. These findings, and clues to what powers the geyser eruptions, are presented in two articles published in the current online edition of the Astronomical Journal. Over a period...

density of interstellar helium

April Flowers for redOrbit.com - Your Universe Online For decades, scientists have been debating over a fog of low-energy X-rays that has been observed over the entire sky. An international group of scientists has used a NASA-funded instrument to resolve this debate. The group refurbished detectors that were first flown on a NASA sounding rocket in the 1970s to confirm that much of this glow is generated by a region of million-degree interstellar plasma known as the local hot bubble (LHB)....

dinosaur asteroid

redOrbit Staff & Wire Reports - Your Universe Online Dinosaurs were victims of bad timing, and likely would have survived the asteroid impact that wiped them out had it occurred slightly earlier or later, researchers from Edinburgh University report in a new study. Dr. Steve Brusatte of the university’s School of GeoSciences and his colleagues explained that dinosaurs were at their most vulnerable when the asteroid hit, as a rising sea level and an increase in volcanic activity...

redOrbit Staff & Wire Reports - Your Universe Online After spending the past four months living and working in a simulated Mars environment in Hawaii, six volunteers emerged from the mock base on Friday, various media outlets reported over the weekend. The individuals, who were participants in the second Hawaii Space Exploration Analog & Simulation (HI-SEAS) mission, spent 120 days before departing from “Mars” and returning to “Earth” at 2pm Eastern time on July 25....

Geometry
2014-01-02 10:21:51

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...

Stellar Astrophysics

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
2012-05-07 07:06:15

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...
