The universe is expanding even faster than we thought

The universe is expanding even faster than we thought The universe is a very big place, and science has proven that it’s only getting bigger as time goes on.Based on the newly published data, it’s happening even faster than we thought.

Celestial fireworks: Hubble observes firestorm of new star formation in an old galaxy

Celestial fireworks: Hubble observes firestorm of new star formation in an old galaxy The infusion of gas into a young galaxy could cause it to become lopsided as star formation picked up faster on one end.Researchers from Vassar College used Hubble’s Wide Field Planetary Camera 3 to observe and analyze some of the few nearby tadpole galaxies like Kiso 5639 in order to confirm this accretion-induced star formation.

Hubble uses gravitational lens to look back at the early universe

Hubble uses gravitational lens to look back at the early universe Those galaxies are from the very early universe, just a billion or so years after the big bang.This creates a natural lens, through which Hubble can look to get a clearer view of objects on the other side.

Gaia, ESA’s revolutionary stellar cartographer, set to transform astronomy

Gaia, ESA’s revolutionary stellar cartographer, set to transform astronomy On September 14, the team will release its first galaxy map, comprising more than two million stars and other objects, and with it a full 19 papers by Gaia astronomers.To deliver this information, Gaia is using one of the oldest techniques in astronomy: parallax, or the extent to which an object seems to move as your position changes.

Astronomers discover true nature of ‘giant space blob’

Astronomers discover true nature of ‘giant space blob’ We’ve been staring at the first such blob, called Lyman-Alpha blob 1 or LAB-1 for short, since we found it in 2000.The birth of galaxies is not a peaceful process, and these young galaxies could be bombarding the star nurseries with high-energy matter, driving star formation.

There may be 10 times more galaxies in the universe than we thought

There may be 10 times more galaxies in the universe than we thought But a new analysis of Hubble Telescope data indicates that astronomers might have vastly underestimated the scale of the universe.There may actually be 10 times more galaxies in the universe than we previously thought.

Can the conflict between dark matter and gravity be resolved?

Can the conflict between dark matter and gravity be resolved? To date, we’ve accounted for this by invoking dark matter and dark energy, which together apparently make up much of the universe.Epicycles accounted for everything we could see — until suddenly we could see more, and that explanation was no longer sufficient.
