FRIDAY 7. JUNE 2013
Noctilucent clouds have surprised researchers by appearing early this year. The unexpected apparition of electric-blue nightshining clouds hints at a change in the "teleconnections" of Earth's atmosphere.
Scientists working with NASA's 70-meter Deep Space Network antenna in Goldstone, Calif., have released a new and improved movie clip of near-Earth asteroid 1998 QE2 and its moon.
THURSDAY 30. MAY 2013
Newly-obtained radar images of approaching asteroid 1998 QE2 reveal that the asteroid has a moon.
NASA is tracking a large near-Earth asteroid as it passes by the Earth-Moon system on May 31st. Amateur astronomers in the northern hemisphere may be able to see the space rock for themselves during the 1st week of June.
Astronomers using data from NASA's Wide-field Infrared Survey Explorer (WISE) have identified 28 new families of asteroids.
FRIDAY 24. MAY 2013
Astronomers using NASA's Spitzer Space Telescope are making weather maps of an exotic class of exoplanets called "hot Jupiters." What they're finding is wilder than anything we experience here in our own solar system.
FRIDAY 17. MAY 2013
NASA researchers who monitor the Moon for meteoroid impacts have detected the brightest explosion in the history of their program. It was caused by a small boulder-sized meteoroid hitting the Moon with as much energy as 5 tons of TNT.
FRIDAY 10. MAY 2013
Mercury, Venus and Jupiter are lining up for a beautiful sunset conjunction at the end of May.

NASA's Cassini spacecraft has spotted a gigantic hurricane swirling inside a mysterious, six-sided weather pattern known as "the hexagon" at Saturn's north pole.
SATURDAY 27. APRIL 2013
NASA's Cassini spacecraft has provided the first direct evidence of small meteoroids crashing into Saturn's rings and breaking into streams of rubble.
THURSDAY 25. APRIL 2013
Saturn and Earth are having a close encounter. See the ringed planet at its best and brightest on April 28th.

FRIDAY 19. APRIL 2013
A new model of the debris flowing from Comet ISON suggests that the sungrazer could dust the Earth with meteoroids in early 2014. Experts discuss the possibilities today's story from Science@NASA.
THURSDAY 18. APRIL 2013
NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.
MONDAY 15. APRIL 2013
A particle detector on board the International Space Station has recorded intriguing signs of Dark Matter. Researchers say that a significant advance in cosmology could be in the offing.
FRIDAY 29. MARCH 2013
Life as we know it doesn't thrive on planets without ozone layers, which is why the recovery of Earth's ozone layer is so important. A new instrument slated for launch to the ISS will monitor our planet's protective ozone cocoon with greater depth and precision than ever before.

THURSDAY 21. MARCH 2013
The European Space Agency's Planck spacecraft has released the most detailed map ever made of the oldest light in the universe, revealing new information about its age, contents and origins.
FRIDAY 15. MARCH 2013
Comet Pan-STARRS has survived its encounter with the sun and is now emerging from twilight in the sunset skies of the northern hemisphere. A NASA spacecraft has beamed back spectacular pictures of a "wild and ragged" tail behind the comet's active nucleus.
TUESDAY 12. MARCH 2013
An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes.
SUNDAY 10. MARCH 2013
Vegetation growth at Earth's northern latitudes increasingly resembles lusher latitudes to the south, according to a NASA-funded study. "It's like Winnipeg, Manitoba, moving to Minneapolis-Saint Paul in only 30 years," says one of the lead researchers.
FRIDAY 8. MARCH 2013
Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers.
SATURDAY 2. MARCH 2013
Something unexpected is happening on the sun. 2013 is supposed to be the year of Solar Max, but solar activity is much lower than expected. At least one leading forecaster expects the sun to rebound with a double-peaked maximum later this year.
