What happens when the planets align? What causes a full moon? What happened to the Arecibo Observatory? How long is the lunar solar cycle? Can two planets crash and cause a supernova? If so, what happens after
Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off by a star as it collapsed to a white dwarf. (Image credit: NASA, ESA, J. Hester, A. Loll (ASU)) Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a ...
What happens at if I look at an eclipse? Looking at a solar eclipse directly or without protection can cause "eclipse blindness" or retinal burns, which can damage or even destroy cells in the retina, negatively affecting your vision. Is it okay to look at a solar eclipse? No, it is ...
What happens during the planetary nebula stage? What happens after the planetary nebula stage? What kind of star is Arcturus? How many known planetary nebula are there? How far away is spiral planetary nebula? What color is a white dwarf? How does a red giant become a planetary nebula? Wha...
10 and 29 solar masses tend to produce neutron stars when they explode. Then there is the theoretical quark star which form when neutron degeneracy breaks down. Anything more dense would create a black hole. So if we continue the progression of degeneracy, what happens when quarks break down?
but it also happens to hold the Guinness World Record for the fastest recorded katabatic wind in history, which was measured in 1912. For reference, katabatic winds are essentially avalanches made of air — a huge air mass that gravity forces down along the terrain when it cools down and ...
is there evidence of the stars in globulars going through nova explosions. Is this not the what happens when low mass stars leave main sequence. Helium fuses to Carbon, and then lacking mass, the star collapses under pressure of gravity. ...
Erik Kuna, has been enthralled by the nebula since he first captured a nebula shot during the CRS-17 launch last year. According to Kuna, most launches can cause stunning light shows, it's just not always as pronounced. "It happens every launch, just some are more prominent than others...
Whilst a star lives, it turns hydrogen into helium and then on to the next element in the periodic table. When fusing gets to Iron, it cannot transform anymore and, as such, dies, first growing into a supergiant and then becoming a Planetary Nebula or if it was massive enough go super...
How are the planets in our solar system organized? What happens after the planetary nebula stage? What happens during the planetary nebula stage? Do planetary systems collide? How is the rotation of Uranus different from other planets? How are gas planets held together? How are all the inner ...
