When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
Once considered as having the largest angular diameter of any star in the sky after the Sun, Betelgeuse lost that distinction in 1997 when a group of astronomers measured R Doradus with a diameter of 57.0 ± 0.5 mas, although R Doradus, being much closer to Earth at about 200 ly, has a linear diameter roughly one-third that of Betelgeuse.

By studying old and dead stars, we can discover what will happen to our sun in the far, far future. And it won't end with a big explosion. By studying old and dead stars, we can discover what will ...
Astronomers are anticipating the appearance of a “new star” triggered by an explosive event that could appear in the night sky anytime between now and September. ‘Once-in-a-lifetime ...
The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10.It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1]
Energy from the explosion is beamed into two narrow, oppositely directed jets. Gamma-ray bursts are very bright as observed from Earth despite their typically immense distances. An average long GRB has a bolometric flux comparable to a bright star of our galaxy despite a distance of billions of light years (compared to a few tens of light years ...

After the sun celebrates its 11 billionth birthday, scientists believe it will continue to expand to the point where it is 166 times bigger than it is now.
