Astronomers discover 3 galaxies from EARLY UNIVERSE

January 18, 2023 -

The three ultra-faint dwarf galaxies (UFDs) are 11.4 million light years way. They are among the most obscure identified outside the Local Group, a clustering of galaxies that includes the Milky Way and Andromeda.

UFDs are the least bright and chemically developed galaxies. They are also dominated by dark matter – the gravitational "glue" scientists think keeps galaxies together. While dark matter has never been directly seen, some ...

Space-time ripples could help scientists uncover exoplanets from other galaxies

August 15, 2020 -

That could change, suggests a recent study, with the use of gravitational waves – invisible ripples in space and time that travel at the speed of light. These waves could get through the obstacles that ordinarily hinder light, which makes them prime targets for detecting extragalactic worlds.

Although gravitational waves are already too weak once they pass through Earth, recent advances in technology allow scientists to better detect gravitational waves. In turn, these ...

A closer look at the voids between galaxies: What’s going on in intergalactic space?

September 09, 2020 -

In between galaxies exists a matter called the intergalactic medium (IGM). This matter – composed mostly of hot, ionized hydrogen, with bits of heavier elements such as carbon, oxygen and silicon thrown in – seemingly exists in only trace amounts in outer space, but when added up actually represents a significant amount of the matter in space.The matter in between galaxies

IGM was discovered in the 1960s when astronomers noticed that light from quasars ...

Space speeding: Astronomers are baffled by 39 ancient galaxies the Hubble could not see

July 13, 2020 -

The Hubble Space Telescope is built to see in ultraviolet, visible and near-infrared light. As they are speeding away from the Milky Way Galaxy, however, these galaxies emit a light that is stretched out into longer and much redder “submillimeter” wavelengths invisible to the Hubble.

Based on the findings, the researchers are beginning to question whether the galaxies that many astronomers focus on, the ones that are motionless enough relative to Earth ...

Astronomers detect the earliest example of a “galactic merger”: The two galaxies spotted crashed together 13 BILLION YEARS ago

February 17, 2020 -

The researchers, who are from Waseda University in Tokyo, believe that the two galaxies, known collectively as B14-65666, began their slow merger when the whole universe was just around a billion years old. This not only makes their merger the oldest known example, but it also makes their two galaxies among the first celestial bodies to ever exist.

Their findings were published in the Publications of the Astronomical Society of Japan.The story ...

Astrophysicist claims that aliens are racing against dark energy, capturing stars from other galaxies, reeling them in, and harvesting their resources

August 30, 2018 -

The reason for their haste is that the energy needs of their civilization would have reached the point where entire stars would only serve as temporary fuel sources for them. And there are only so many stars in a galaxy that are suitable for harvesting.

Fermi National Accelerator Laboratory (FermiLab) researcher Dan Hooper wrote in his paper that galaxies that are not tethered by gravity to our own galaxy will go past the cosmic horizon of Earth in a hundred ...
