Earth will probably not even exist when the sun dies. The sun is slowly expanding. In about 5 billion years, the sun will enter the red giant phase. During this phase, the sun makes a transition from burning hydrogen in the core to burning hydrogen around the core, which has been conver...
A supernova isa massive explosion of a dying star. The event occurs during the last evolutionary stages of a massive star, which is dying. The explosions are extremely bright and powerful. The star, after explosion, turns into a neutron star or a black hole, or is completely destroyed. Why...
What will we lose when the telescope finally dies? NASA is quick to point out that the James Webb Space Telescope, expected to launch in 2018, will enhance Hubble's capabilities in many ways. But for the telescope's higher resolution and ability to peer back to the very early days of ...
that we can map that out over time, is amazing. I don’t even know if I really talked about this in the book, but when we look at very distant supernovae, solar explosions, they appear to be happening more slowly if they’re far away, because the expansion of the universe stretches...
To justify the late time cosmic acceleration detected by the Ia supernova observations [12], one is required to modify either the 'gravity part' or the 'matter/stress energy part' of the Einstein field equation. The latter initiated the idea of modelling dark energy (DE) which is a kind ...

have been able to identify a possible GRB candidate. AWolf-Rayet Star (WR 104). located about 8,000 light-years away is likely to explode into a supernova in 500,000 years. When it does, a GRB will occur. There is only a small chance that our planet will be in the path of its...
