Our Moon, the Cosmic Ray Detector

The moon provides an easy way to detect rare ultra-high-energy cosmic rays.

To the Center of The Cold Spot

Astronomers measure the randomness in the Cosmic Microwave Background radiation to determine the cause of an anomalously cold spot.

The Echoes of a Supernova

Spectra from the light echoes of distant supernovae can be used to probe the three dimensional structure of these massive and poorly-understood explosions.

Information Preservation and Weather Forecasting for Black Holes

Stephen Hawking proposes that black holes may not have definite event horizons, meaning they’re really more like “gray” holes.

Observing the Next Galactic Supernova

Supernovae happen in the Milky Way at a rate of two or three per century. But, will we be able to see it when it happens next, or will dusty galactic center prevent us from studying it?

Fishing For Neutrinos

A neutrino detector sits on the floor of the Mediterranean Sea whose goal it is to identify neutrinos from high-energy astrophysical sources.

How to Drag an Asteroid to Earth

With some assistance from gravity, it is possible with currently-available technologies to bring small asteroids into orbit next to Earth to be studied and mined.

Cartography of the Local Cosmos

Astronomers map out the local universe in a way that is both intuitive and fascinating, marking the birth of the new science of “Cosmography”.

The Great Disco Ball in the Sky

Frame Dragging is a phenomenon predicted by General Relativity, but its effects have been difficult to measure. A small, round satellite called LARES aims to change that.

Why Does Nature Form Exoplanets So Easily?

Title: Why Does Nature Form Exoplanet Easily Author: Kevin Heng Institution: University of Bern, Center for Space and Habitability It’s an exciting time for planet hunters. Over the last few years, the search for extrasolar planets (“exoplanets” for short) has become one of the hottest topics in astronomy. During every exoplanet talk that I’ve attended […]
