A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. The event, which could occur anytime between now and September, is creating a buzz within ...
Region 3500 on our Sun just fired a near X-class flare and launched a strong Earth-directed #solarstorm. Waiting for coronagraph imagery, but it looks like this storm could arrive by December 1.
Astronomers have taken the first close-up image of a star beyond our galaxy, and it’s a “monster star” surrounded by a cocoon as it slowly dies.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (less than roughly 10 to 300 parsecs [33 to 978 light-years] away [2]) to have noticeable effects on Earth's biosphere.
The supernova was a Type Ic supernova, similar to SN 1998bw, the first supernova linked to a GRB. Lightning detectors in India and Germany picked up signs that the Earth's ionosphere was perturbed for several hours by the burst, though only mildly, [ 37 ] [ 17 ] [ 4 ] as well as an enormous influx of electrically charged particles, [ 38 ...
The supernova exploded when the universe was 3.5 billion years old, rather than at today's date of 13.8 billion years old. The supernova progenitor was a white dwarf star, the progenitor of all Type Ia supernovae. The gravitational lens is galaxy cluster PLCK G165.7+67.0 (at a redshift of z=0.35), which lensed the supernova and its host galaxy ...
Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. "Even as a star dies, its light endures ...
Stars with an initial mass up to about 90 times the Sun, or a little less at high metallicity, result in a type II-P supernova, which is the most commonly observed type. At moderate to high metallicity, stars near the upper end of that mass range will have lost most of their hydrogen when core collapse occurs and the result will be a type II-L ...
