The six-member crew of the International Space Station took shelter in two Russian Soyuz spacecraft early Tuesday because of a predicted close approach by an unknown piece of space debris.Safety procedures are put into effect when radar tracking indicates debris
Newly-discovered asteroid 2011 MD will pass only 12,000 kilometers (7,500 miles) above Earth’s surface on Monday June 27 at about 1:00 p.m. EDT (1700 UT).
A fast-moving stream of solar wind is buffeting Earth’s magnetic field. The combined effect of this stream plus a CME expected to arrive on June 24th has prompted NOAA forecasters to declare a 30% to 35% chance of geomagnetic storms during the next 24 hours.
Newly-discovered asteroid 2011 MD will pass only 12,000 kilometers (7,500 miles) above Earth’s surface on Monday June 27 at about 9:30 a.m. EDT. NASA analysts say there is no chance the space rock will strike Earth. Nevertheless, the encounter is so close that Earth’s
A fast-moving stream of solar wind is buffeting Earth’s magnetic field. The combined effect of this stream plus a CME expected to arrive soon has prompted NOAA forecasters to declare a 30% to 35% chance of geomagnetic storms on June 23-24. High-latitude sky watchers
A CME propelled toward Earth by the “solstice solar flare” of June 21st may be moving slower than originally thought. Analysts at the GSFC Space Weather Lab have downgraded the cloud’s probable speed from 800 km/s to 650 km/s. Impact is now expected on June 24th at
Magnetic fields above sunspot complex 1236 erupted during the early hours of June 21st, producing a C7-class solar flare and a full-halo CME. The expanding cloud appears to be heading almost directly toward
Astronomers have spied a star’s swan song as it is shredded by a black hole. Researchers suspect that the star wandered too close to the black hole and got sucked in by the huge gravitational forces. The star’s final moments sent a flash of radiation hurtling towards
The magnetic field of sunspot 1236 harbors energy for M-class solar flares. NOAA forecasters estimate a 25% chance of such an eruption during the next 24 hrs.
On June 14th around 08:10 UTC, a magnetic filament near the sun's eastern limb became unstable and erupted. The resulting blast hurled a bright and massive CME into space. The expanding cloud was observed by 3 spacecraft: STEREO-A, STEREO-B and SOHO. Researchers…
