Professional And Amateur Astronomers Join Together
2014-04-24 03:21:06

NASA Long before the term "citizen science" was coined, the field of astronomy has benefited from countless men and women who study the sky in their spare time. These amateur astronomers devote hours exploring the cosmos through a variety of telescopes that they acquire, maintain, and improve on their own. Some of these amateur astronomers specialize in capturing what is seen through their telescopes in images and are astrophotographers. What happens when the work of amateur...

2014-04-23 11:21:39

The Kavli Foundation The world was stunned by the recent announcement that a telescope at the South Pole had detected a cosmic fossil from the earliest moments of creation; During a live Google Hangout, 4 astrophysicists discussed the implications Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. This almost unimaginably fast expansion was first theorized more...

Sentinel Telescope May Help Save Us From Earth-Killing Asteroids
2014-04-23 08:04:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood. But in the modern world, are the impacts portrayed in movies like Deep Impact and Armageddon only the stuff of science fiction? The answer is likely no. Scientists continue to warn us of the dangers that lurk in the skies above us and in the past dozen or so years, no less than 26...

Pair Of Supermassive Black Holes Discovered By XMM-Newton
2014-04-22 14:09:30

ESA A pair of supermassive black holes in orbit around one another have been spotted by XMM-Newton. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction. Most massive galaxies in the Universe are thought to harbor at least one supermassive black hole at their center. Two supermassive black holes are the smoking gun that the galaxy has merged with...

Mysteries Of Nearby Planetary System's Dynamics Are Now Solved
2014-04-22 12:33:58

Penn State Mysteries of one of the most fascinating nearby planetary systems now have been solved, report authors of a scientific paper to be published by the journal Monthly Notices of the Royal Astronomical Society in its early online edition on 22 April 2014. The study, which presents the first viable model for the planetary system orbiting one the first stars discovered to have planets -- the star named 55 Cancri -- was led by Penn State University graduate student Benjamin Nelson in...

Looking At Earth From Orbit: 2013
2014-04-22 10:58:27

[ Watch The Video: NASA Sees Earth From Orbit: 2013 ] NASA A fleet of orbiting satellites monitors Earth constantly. The satellites from NASA and other space agencies give us a fresh, wide perspective on things that we can see from the ground – and things that we can’t. A look back at Earth in 2013 from the viewpoint of orbit reveals the kind of data gathering and technical achievement that are the reason NASA puts Earth-observing satellites in space. A visualization of...

Fireball Flying Over Northern Russian City Caught On Vehicle Dash Cam
2014-04-22 06:59:42

Lawrence LeBlond for redOrbit.com - Your Universe Online A suspected meteorite explosion has been recorded by citizens of the northern Russian city of Murmansk over the weekend. The fireball left a noticeable bright blue trail as it sped across the night sky at about 2:14 am (local time) on Saturday, before ending in explosion, according to multiple witnesses. There were no reports of damage during this weekend’s encounter, yet the fireball did raise some eyebrows due to its eerily...

Plant Material Stored In Impact Glass Could Reveal Much About Ancient Earth, Mars
2014-04-20 07:04:38

redOrbit Staff & Wire Reports - Your Universe Online The discovery of biodata encapsulated in molten glass resulting from asteroid and comet impacts millions of years ago not only provides information about the climate and life forms of the ancient Earth, but has also led to hopes that similar preserved organic compounds will be discovered on Mars. Fragments of leaves and other organic compounds were found lodged inside glass created by ancient impacts in Argentina by Brown...

Whitney Clavin, NASA Jet Propulsion Laboratory The New Mexico Exoplanet Spectroscopic Survey Instrument (NESSI) will soon get its first "taste" of exoplanets, helping astronomers decipher their chemical composition. Exoplanets are planets that orbit stars beyond our sun. NESSI got its first peek at the sky on April 3, 2014. It looked at Pollux, a star in the Gemini constellation, and Arcturus, in the Boötes constellation, confirming that all modes of the instrument are working....

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...
