Astronomers predict that the nova explosion could happen anytime between now and September. The last time this particular star system erupted was in 1946, Schaefer said, and another eruption will ...
The explosion should be visible to the unaided eye for several days and just over a week with binoculars before it dims again. Keep an eye out online for reports that the explosion has occurred.
Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
The Space Weather Prediction Center ... that happened on the sun’s surface on Dec. 29. A CME explosion is caused by the sun’s magnetic field and, like in this case, can sometimes result in ...
The solar wind's equivalent of a sonic boom in the solar-system plasma medium can accelerate protons up to millions of miles per minute – as much as 40 percent of the speed of light. [ citation needed ] This is a proven source of auroras , but has never yet been shown to be sufficiently forceful and sufficiently abrupt to cause a "boom".
Meteoroids enter the Earth's atmosphere from outer space traveling at speeds of at least 11 km/s (7 mi/s) and often much faster. Despite moving through the rarified upper reaches of Earth's atmosphere the immense speed at which a meteor travels rapidly compresses the air in its path.
The Geminid meteor shower peak is a week away, but this year it might be a good idea to keep an eye out early, according to NASA. Dedicated skywatchers might want to check the sky not only in the ...
Until 2012, it was not known whether the possible collision was definitely going to happen or not. [9] Researchers then used the Hubble Space Telescope to measure the positions of stars in Andromeda in 2002 and 2010, relative to hundreds of distant background galaxies. By averaging over thousands of stars, they were able to obtain the average ...
