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 […]

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 […]

New Image of the Craters within the Hellas Basin of Mars

This newly released Mars Express image shows craters within the Hellas Basin in the southern highlands of Mars. Scarring the southern highlands of Mars is one of the Solar System’s largest impact basins: Hellas, with a diameter of 2300 km and a depth of over 7 km. Hellas is thought to have formed between 3.8 […]

Astronomers Accurately Measure a Black Hole that is 400 Times the Mass of Our Sun

A team of astronomers from the University of Maryland has accurately measured a black hole in galaxy M82, revealing that is about 400 times the mass of our sun. The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our […]

New Detailed Image of 67P Churyumov Gerasimenko

Taken by ESA’s Rosetta Spacecraft, this new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet’s nucleus. The image was taken by the Rosetta spacecraft’s OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65 miles (104 kilometers) away from the 2.5-mile-wide (4-kilometer) nucleus. In the image, […]
