Scientists have taken a close-up picture of a star apparently in its death throes, surrounded by gas and dust as it heads toward its demise in a huge explosion called a supernova - the first time ...
Boom.In the colossal Pinwheel galaxy, 25 million light-years away, a star has just exploded and is even visible through small telescopes. The supernova-hunting astronomer Koichi Itagaki discovered ...
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.
The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
The hypothetical colonization of Mars has received interest from public space agencies and private corporations and has received extensive treatment in science fiction writing, film, and art. While there have been many plans for a human Mars mission , including affordable ones such as Mars Direct , none has been realized as of 2024.
The expansion shell has a temperature of around 30 million K, and is expanding at 4,000−6,000 km/s. [2]Observations of the exploded star through the Hubble Space Telescope have shown that, despite the original belief that the remnants were expanding in a uniform manner, there are high velocity outlying eject knots moving with transverse velocities of 5,500−14,500 km/s with the highest ...
For the first time, astronomers have observed the final days and death throes of a red supergiant star before its final collapse and massive explosion into a
Ultra-stripped supernovae occur when the exploding star has been stripped (almost) all the way to the metal core, via mass transfer in a close binary. [130] [131] As a result, very little material is ejected from the exploding star (c. 0.1 M ☉). In the most extreme cases, ultra-stripped supernovae can occur in naked metal cores, barely above ...
