Astronomers Reveal the Mysteries of Supernova 2014J in Galaxy M82

Astronomers used a vast network of radio telescopes to obtain many images of supernova 2014J, revealing a lack of radio emission from the supernova and providing scientists the opportunity to learn more about these extremely important astrophysical phenomena and their underlying cause. The supernova, a giant explosion of a star and the closest one to […]

Researchers Discover a New Gravitational Wave Source

Astronomers from the Harvard-Smithsonian Center for Astrophysics have detected a pair of white dwarf stars that orbit in about 20 minutes and that can be used as a verification source for gravitational wave missions. Einstein’s general theory of relativity predicts that accelerating masses should radiate gravity waves in a roughly similar way that accelerating electrical […]

Voyager Maps Neptunes Moon Triton

The Lunar and Planetary Institute used Voyager’s 1989 historic footage of Neptune’s moon Triton to construct the best-ever global color map of the strange moon. NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager’s historic footage of Triton has […]

LOFAR Observes Cosmic Particles in Galaxy M51

Using the LOFAR High Frequency Antennas, a team of researchers has observed cosmic particles and magnetic fields in spiral galaxy M51. The object Messier 51 (M51), seen from a distance of approximately 30 million light years, is also referred to as the whirlpool galaxy because of its appearance. The ‘whirlpool’ appears almost face-on and displays […]

Solar Energetic Particles May Have Altered the Properties of Lunar Soil

New research shows that high-energy particles from large solar storms can penetrate the moon’s polar regions and electrically charge the soil, causing electrostatic breakdown and altering the properties of the soil on the moon. The moon appears to be a tranquil place, but modeling done by University of New Hampshire (UNH) and NASA scientists suggests […]

Composite Images Shows Results of a Mighty Supernova Explosion

This composite image shows the remnant of a supernova that would have been witnessed on Earth 3,700 years ago. This image from the Chandra X-Ray Observatory, NASA’s Spitzer Space Telescope and the European Space Agency’s XMM-Newton reveals the destructive results of a mighty supernova explosion in a delicate blend of infrared and X-ray light. The […]

Research Shows Two Dynamos Drive Jupiters Magnetic Feld

With the aid of the computer simulations, a team of scientists has now succeeded in explaining the origin of the magnetic field deep inside Jupiter. Superlatives are the trademark of the planet Jupiter. The magnetic field at the top edge of the cloud surrounding the largest member of the solar system is around ten times […]

New Observations of the Type Ia SN 2014J in Galaxy M82

A newly published study from the Institute of Astrophysics of Andalusia discards possibility that type Ia supernovae might stem from explosions of white dwarfs nourished by normal stars. Were these conclusions to become generalized, type Ia supernovae might no longer serve as “standard candles” to measure astronomical distances. Type Ia supernovae happen when a white […]

New Image Reveals Two Dramatic Star Formation Regions in the Southern Milky Way

This new image from the European Southern Observatory shows two dramatic star formation regions (NGC 3603 and NGC 3576) in the southern Milky Way. This image, captured by the Wide Field Imager at ESO’s La Silla Observatory in Chile, shows two dramatic star formation regions in the southern Milky Way. The first is of these, […]

Curiosity Image of Bonanza King Target

This newly released image from NASA’s Curiosity Rover shows a gray patch of rock material at the “Bonanza King” location. NASA’s Curiosity Mars rover used the Dust Removal Tool on its robotic arm to brush aside reddish, more-oxidized dust, revealing a gray patch of less-oxidized rock material at a target called “Bonanza King,” visible in […]

NASAs RXTE Satellite Uncovers the Rhythm of an Unusual Black Hole

A team of astronomers has uncovered rhythmic pulsations from a rare breed of black hole in archival data from NASA’s Rossi X-ray Timing Explorer satellite. The signals provide compelling evidence that the object, known as M82 X-1, is one of only a few midsize black holes known. Explore M82 X-1 and learn more about how […]
