Dark comets are comets that are so small, fast and/or chemically rare that they are difficult to see from Earth

NASA has prepared a truly stellar gift - a new image of the star cluster NGC 602, located 200,000 light-years from Earth. The new image is the result of collaboration between some of the most advanced space telescopes in the world.

The cosmos began expanding with the Big Bang but then around 10 billion years later it strangely began to accelerate thanks to a theoretical phenomenon termed dark energy. Credit: NASA One of science’s biggest mysteries is dark energy.

NASA astronauts Sunita "Suni" Williams and Barry "Butch" Willmore were expected to return home in February after their extended stay at the ISS, but NASA confirmed the two will be in space longer.

Dark matter's mass limit increased by an order of magnitude, impacting our understanding of the universe's invisible substance.

The Nancy Grace Roman Space Telescope team at NASA has completed the integration of the telescope and its instruments onto the carrier, a significant milestone in the assembly process. With the Coronagraph Instrument and the Optical Telescope Assembly in place,

In case dark matter didn't seem mysterious enough, a new study proposes that it could have arisen before the Big Bang.

NASA will resume its annual long-duration balloon operation in Antarctica by launching two flights in mid-December for planned nine missions to near space.

Find out about the recent developments regarding the Roman Space Telescope and how they might bring us closer to understanding the universe.

Some of this stuff is known as mysterious dark matter, others are things like dark comets, which as their name suggests, are far more difficult to see from Earth than something like Tsuchinshan-Atlas.

New measurements from the James Webb Space Telescope suggest that a discrepancy in the observed expansion rate of the universe could be down to the influence of dark energy
