dark matter

The universe is expanding 9 percent more quickly than expected, telling us there’s something we’re missing. Could it be a new type of particle?

A plethora of missing matter problems besieges astronomy.

The dinosaur extinction 66m years ago was most likely caused by a comet or big asteroid hitting the Earth.

By measuring the mass of a nearby dwarf galaxy called Triangulum II, researchers may have found the highest concentration of dark matter in any known galaxy.

The humble neutrino particle won its fourth Nobel Prize in physics this year (also in 2002, 1995 and 1988).

Long before we had the atomic theory of matter, scientists knew the air was real, even though it was invisible.

Only about 5% of the universe consists of ordinary matter such as protons and electrons, with the rest being filled with mysterious substances known as dark matter and dark energy.

Astronomers have discovered a giant swirling disk of gas 10 billion light-years away—a galaxy-in-the-making that is actively being fed cool primordial gas tracing back to the Big Bang.

After two-years of upgrades and repairs, the Large Hadron Collider is back in the particle-smashing business—this time at double the energy of its first run.

The nature of dark energy is one of the most important unsolved problems in all of science. But what, exactly, is dark energy, and why do we even believe that it exists?

Astronomers have found evidence of a giant void that could be the largest known structure in the universe.

Dark matter is the most common stuff in the universe. Now, studies are beginning to shed some light on this mysterious substance.

We can map it, weigh it and simulate it, yet we still have no idea what it is. But dark matter is coming into the spotlight as never before.

A newly discovered dwarf galaxy orbiting the Milky Way appears to be radiating gamma rays—a sign that dark matter may be lurking at the galaxy’s center.

The Earth’s infrequent but predictable path around and through our galaxy’s disc may have a direct and significant effect on geological and biological phenomena on Earth, according to new research.
