okay so inside stars, the energy coming from the fusion of elements oppose against the gravity pulling in. they balance each other out but as that star gets older and when the fusion of heavier elements starts, energy from the star is not enough to balance the force of gravity so gravity eventually wins and the star gets smaller and smaller. and these heavier elements, most importantly iron, are the dead end for stars.

and the fact that we are able to live because of iron in the first place gives me goosebumps. it’s found in hemoglobin which carry oxygen around our body, it’s needed for proper immune function, and it has many more jobs to do in our fragile organic matter body.

just think about that for a second. the universe is so strange and so are humans.

it’s weird to be alive.

Does anyone ever just stop and realize - DAMN what a time we live in.

It’s 2020 and we just launched a SpaceX Falcon 9 rocket into space with humans on it, landed the main rocket back on Earth successfullyy, on an OCEAN barge!?

And meanwhile you see the crew room where an entire team of people is wearing face masks and social distancing as they do their job.

What. A. Time.

Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. The new type of explosion shares some characteristics with supernova explosions of massive stars and with the explosions that generate gamma-ray bursts (GRBs), but still has distinctive differences from each.

The saga began in June of 2018 when astronomers saw a cosmic blast with surprising characteristics and behavior. The object, dubbed AT2018cow (“The Cow”), drew worldwide attention from scientists and was studied extensively. While it shared some characteristics with supernova explosions, it differed in important aspects, particularly its unusual initial brightness and how rapidly it brightened and faded in just a few days.
