Dark Matter

by Chris Shallue figures by Fiona Qu There’s an equation engraved on Stephen Hawking’s gravestone in Westminster Abbey: This unassuming equation, discovered by Hawking in 1975, has extraordinary implications. It suggests that black holes,…

Scientists use archival images of Jupiter to search for dark matter collisions.

A new study shows that the universe is expanding faster than scientists had initially predicted, sparking an effort to determine what unknown force in space is responsible. Read Ben Andreone’s article to learn more!

Everyone on Earth is familiar with gravity to some extent; it is the force that pulls us down to the planet’s surface. In fact, all objects with mass tug on other objects moving around them because of gravity. The strength of the gravitational pull…

by Daniel Ang figures by Aparna Nathan Particle physics says that the universe shouldn’t exist. This is a radical claim! But if the current theories that underlie particle physics are correct and complete, then the Big Bang that birthed the universe…

by Sasha Brownsberger figures by Abagail Burrus Everything you have ever touched, seen, or tasted; the air you breathe; the ground on which you stand; and the constituents of your body all consist of a type of matter that is only a fraction of all that…

The AMS Experiment on the International Space Station In 2011 the Alpha Magnetic Spectrometer, or AMS, was launched into space. AMS, housed by the International Space Station and led by a Nobel Prize winning principle investigator, is commonly referred…

Historically, galactic rotation curves have suggested that galaxies are surrounded by a vast amount of invisible matter, otherwise known as a dark matter halo. A few weeks ago, a team of astrophysicists published a result that completely contradicts…

Astronomers used the Gemini Telescope to photograph Dragonfly 44, an ultra diffuse galaxy comprised of almost entirely dark matter. Last week, astronomers announced the discovery of a galaxy that is almost entirely comprised of dark matter. At first…

At the 11th Identification of Dark Matter Conference, LUX, the Large Underground Xenon experiment, announced the results of the world’s most sensitive search for dark matter. Physicists at LUX have been racing for a dark matter discovery since the…
