supernova 1993J
2014-09-10 04:07:05

April Flowers for redOrbit.com - Your Universe Online After two decades of searching, astronomers using NASA's Hubble Space Telescope have discovered a companion star to a rare type of supernova — confirming a long-held belief that supernova SN 1993J occurred inside of a binary system. A binary system involves two stars interacting with each other, and in this case, causing a cosmic explosion. "This is like a crime scene, and we finally identified the robber," said Alex Filippenko,...

WASHINGTON, Sept. 9, 2014 /PRNewswire-USNewswire/ -- Using NASA's Hubble Space Telescope, astronomers have discovered a companion star to a rare type of supernova. The discovery confirms a long-held theory that the supernova, dubbed SN 1993J, occurred inside what is called a binary system, where two interacting stars caused a cosmic explosion. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "This is like a crime scene, and we finally identified the robber," said Alex...

Donna McKinney, Naval Research Laboratory Dr. John Carr, a scientist at the U.S. Naval Research Laboratory (NRL), is part of an international team that has discovered what they believe is evidence of a planet forming around a star about 335 light years from Earth. This research is published in the August 20th issue of The Astrophysical Journal. Carr and the other research team members set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in...

plate tectonics on Europa
2014-09-08 12:06:43

NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

listening to the sun
2014-09-04 12:25:52

Kasha Patel, NASA’s Goddard Space Flight Center Robert Alexander spends parts of his day listening to a soft white noise, similar to water falling on the outside of a house during a rainstorm. Every once in a while, he hears an anomalous sound and marks the corresponding time in the audio file. Alexander is listening to the sun’s magnetic field and marking potential areas of interest. After only ten minutes, he has listened to one month’s worth of data. Alexander is a PhD...

asteroid visitor
2014-09-04 09:04:03

NASA A small asteroid, designated 2014 RC, will safely pass very close to Earth on Sunday, Sept. 7, 2014.  At the time of closest approach, based on current calculations to be about 2:18 p.m. EDT (11:18 a.m. PDT / 18:18 UTC), the asteroid will be roughly over New Zealand.  From its reflected brightness, astronomers estimate that the asteroid is about 60 feet (20 meters) in size. Asteroid 2014 RC was initially discovered on the night of August 31 by the Catalina Sky Survey near Tucson,...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
