If dark matter is discovered through one of these experiments or another that hasn’t yet been dreamed up, it could essentially shed a light on an entire hidden universe that for now remains a mystery, said Dr. Tracy Slatyer, a theoretical particle physicist at the Massachusetts Institute of Technology.

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

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.

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,

Dec. 20, 2024 — One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding.

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

Dark matter, an enigmatic and invisible substance that constitutes approximately 85% of the mass in the universe, remains one of the most compelling mysteries in modern physics. Despite its widespread presence in the cosmos,

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.

For millions of years following the Big Bang, after the universe’s roiling soup of particles had cooled, the cosmos was a dark and boring place. There were no stars to make light. No familiar swirls of galaxies.

HE0435-1223, a lensed quasar, is surrounded by four images created by a foreground galaxy, making it one of the five best lensed quasars discovered. Hubble's image of NGC 5793, a spiral galaxy 150 million light-years away, highlights its striking dust lane and exceptionally bright center, much brighter than our galaxy's.
