April Flowers for redOrbit.com - Your Universe Online Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. Filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles, according to a new study released by astronomers using the National Science Foundation's (NSF) Green Bank Telescope (GBT). These pebbles are planetary building blocks 100 to 1,000 times larger than the dust...

light in the real cosmos
2014-08-27 12:04:57

Rebecca Caygill, University College London New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built. The study published today in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal...

Dr. Tony Phillips, Science@NASA Once every 50 years, more or less, a massive star explodes somewhere in the Milky Way. The resulting blast is terrifyingly powerful, pumping out more energy in a split second than the sun emits in a million years. At its peak, a supernova can outshine the entire Milky Way. It seems obvious that you wouldn't want a supernova exploding near Earth. Yet there is growing evidence that one did — actually, more than one. About 10 million years ago, a nearby...

galaxy collision

Chuck Bednar for redOrbit.com - Your Universe Online Using a battery of observatories that included the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope, an international team of astronomers has obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age. According to ESA, the team also utilized a gravitational lens to magnify galaxy HATLAS J142935.3-002836, revealing...

Eta Carinae
2014-08-27 05:41:19

NASA's Marshall Space Flight Center The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future. [ Watch the Video: Eta Carinae: Our Neighboring Superstars ] As one of the first objects observed by NASA’s Chandra X-ray Observatory after its launch some 15...

New Electro-Optical Tracking Site to Complement Radar Tracking Systems DENVER and CANBERRA, Australia, Aug. 25, 2014 /PRNewswire/ -- Under a new strategic cooperation agreement, Lockheed Martin [NYSE: LMT] and Electro Optic Systems Pty Ltd are developing a new space object tracking site in Western Australia that will paint a more detailed picture of space debris for both government and commercial customers. The site will use a combination of lasers and sensitive optical systems...

New Horizons view of Neptune
2014-08-25 13:01:28

NASA/JPL NASA's Pluto-bound New Horizons spacecraft has traversed the orbit of Neptune. This is its last major crossing en route to becoming the first probe to make a close encounter with distant Pluto on July 14, 2015. The sophisticated piano-sized spacecraft, which launched in January 2006, reached Neptune's orbit -- nearly 2.75 billion miles (4.4. billion kilometers) from Earth -- in a record eight years and eight months. New Horizons' milestone matches precisely the 25th anniversary...

solar flare
2014-08-25 10:43:47

Karen C. Fox, NASA's Goddard Space Flight Center On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and...

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
2014-01-12 00:00:00

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

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...
