Data from the Hubble space telescope suggests that enormous jets of water, more than 200 kilometers tall, may be spurting intermittently from the surface of Europa, ice-shelled moon of Jupiter.
Although it’s been known since 2005 that
At this year's Fall Meeting of American Geophysical Union, held in San Francisco (December 9 – 13), several scientists made a presentation on weak Solar Cycle 24 and its consequences.
They agree that the current solar cycle is on track to be
Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole.
This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of
The Canadian Meteor Orbit Radar (CMOR) is detecting an outburst of Andromedid meteors today.
"Meteor rates last night were near 20 per hour (ZHR)," reports Bill Cooke of NASA's Meteoroid Environment Office. "The shower could increase in
In November 2013, skywatchers around the world eagerly awaited the approach of Comet ISON. Dubbed the "Comet of the Century" by several in the media, some astronomers had predicted a stupendous cometary display as Comet ISON approached its perihelion.
The
The past few weeks have been an unusually active time for comet watchers as four comets were visible simultaneously with binoculars: ISON, Lovejoy, Encke, and LINEAR.

Earth is entering a stream of debris from Comet 3200 Phaethon, source of the annual Geminid meteor shower. This year's meteor shower peak is expected around December 13/14. Visual meteor rates are still low, but first meteorids will start appear in
The most intense electromagnetic event known to occur in the heavens is the gamma-ray burst. For many years, scientists have claimed that most gamma ray burst occur when stars run out of nuclear fuel then collapse to form a black hole, neutron star or quark star.
The presence of atmospheric water was reported previously on a few planets orbiting stars beyond our solar system, but a paper published yesterday in Astrophysical Journal is the first one that conclusively measured and compared the profiles and
Launched by a Vega rocket from French Guiana in the early hours of May 7, 2013, the Proba-V miniaturised satellite is designed to map land cover and vegetation growth across the entire planet every two days at a resolution of 330 m.
Today, less than seven months
