At some point during the next several months, a distant, dead star will rapidly grow brighter in a powerful explosion, making it visible from Earth for a short period of time. To observers on the ground, it will look like a new star. The dead star—which...
When a star with a core equal to 3 solar masses or more explodes, the aftermath of its explosion can result in a black hole. Scientists hypothesize that black holes form when gravity causes a star's compressed inner core to continually sink into itself. A black hole has such a powerful ...
A nova is a powerful eruption from star, but is not as strong as a supernova, which is a catastrophic explosion that signals the death of a star. Weather permitting, you can see the star explosion in a webcast on SPACE.com tonight, courtesy of the online Slooh Space Camera. The ...
IEDs may also be used as the explosive part of a biological or radioactive dirty bomb. Let's look at how these parts work together: The power source supplies electricity to the trigger or switch and to the detonator. The trigger activates the detonator and initiates the explosion sequence. ...
How do you determine the magnitude of acceleration for 2 masses on a pulley? How does the length of a pendulum affect the period of the pendulum? The compressed core of a star formed in the wake of a supernova explosion consists ...
We don't know what came beforethe universe and we don't know what started it, but we do know it started withthe Big Bang. Oh no, is that about to happen? Couple you is don't worry, itwasn't actually a bang. It wasn't an explosion at all. ...
确实产生了supernova explosions didcreate some一些较重的元素of the heavier elements.但从我们对所有超新星的观察来看But from everythingwe've observed about supernova,它们发生的频率还不足以让我们观察到they don't happen often enoughto really populate a galaxy在一个星系中形成的所有较重的元素with all...
This kind of star fuses heavier and heavier elements in its core, eventually becoming so massive that it cannot hold itself up against gravity, Borowski said. The result is a huge explosion called a supernova. Thestar's core lives on as either a neutron star or a black hole, according to...
How does space junk affect us? If space junk collides with another body, it can break off and produce more fragments. There is a possibility this junk in orbit will eventually be pulled down by Earth's gravity. Can we see Earth live from satellite? Yes, you can now watch livestreams ...
And a universe that reaches equilibrium and does nothing will become a "big bore." The Role of Dark Energy Pictured and magnified here on the left is a supernova that Hubble caught on camera that exploded 10 billion years ago. Called 1997ff, it greatly bolstered the case for the ...
