We are all made of comet dust
By Robert Matthews | The National Man owes a lot to chunks of rock and ice floating through space. From ancient jewellery to water and possibly even the beginnings of life itself, scientists are discovering that comets have contributed in many ways to the development of life on the planet, Robert Matthews writes Since their discovery [...]

By Tibi Puiu | ZMEscience If you’re a regular follower of NASA’s updates, you may have caught glimpses of some of the X-ray photos they report showing the surface of the sun. In these photos, dark specks of various sizes can be seen, which are actually what astronomers refer to as coronal holes. They may extend from the [...]

By Miriam Kramer | Space.com Tiny telescopes in Arizona and South Africa have spotted a Saturn-like planet in orbit around a star about 700 light-years from Earth. Scientists using the Kilodegree Extremely Little Telescope (KELT) and other ground-based tools spied the alien planet as it passed in front of its star, a process called transiting. The planet, [...]

By Irene Klotz | Discovery A radiation sensor inside NASA’s Curiosity Mars rover shows that even under the best-case scenario and behind shielding currently being designed for NASA’s new deep-space capsule, future travelers will face a huge amount of radiation. The results, based on Curiosity’s 253-day, 348-million-mile cruise to Mars, indicate an astronaut most likely [...]

Earth is pushing the moon away faster now than it has for most of the past 50 million years, mostly a result of tides, a U.S. researcher says.

By Marc Bouche | SpaceRef New radar data obtained by NASA shows Asteroid 1998 QE2 has a moon. The asteroid will get no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. The new radar data was obtained on May 29th when the asteroid was [...]

By Markus Hammonds | DNews Magnetars are a rare type of neutron star, with powerful magnetic fields making them prone to occasional violent outbursts. Only a small handful of these curious beasts have been found in our galaxy, but new research from the Chandra X-ray Observatory implies that they may be a lot more common than previously expected. [...]

By Chillymanjaro | The Watchers Millions of infrared snapshots from NASA’s Wide-field Infrared Survey Explorer (WISE) have led to a new and improved asteroid family members in the main belt between Mars and Jupiter. NEOWISE all-sky survey identified 28 new asteroid families. The next step for the team is to learn more about the original parent bodies that spawned the [...]

By Greg Laden | Science Blogs There are bacteria that use Iron (and other elements) to make tiny magnets that they carry around so they don’t get lost. (I anthropomorphize slightly.) There are isotopes of Iron that are not of the Earth, but are found only elsewhere in the universe. Suppose an event happened elsewhere and [...]

University of Leeds | eScience Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun. Scientists have known since the 18th Century that the Sun regularly oscillates between periods of high and low solar activity in an 11-year cycle, [...]

By Red Ice Creations Sun watchers’ faces might well be melting off with all the activity that’s been bursting forth from the sun over the last forty-eight hours. In the increasing solar activity that’s ramping up to peak during 2013, our star has been releasing dramatic and powerful bursts of radiation into space – reportedly [...]

Spaceweather A sunspot hiding behind the sun’s northeastern limb erupted on May 13th at 02:17 UT, producing the strongest solar flare of the year so far.NASA’s Solar Dynamics Observatory recorded the extreme UV flash from the X1.7-class eruption: Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) tracked a bright CME emerging from the blast site.
