‘Space Warps’ and other citizen science projects reap major dividends for astrophysics

The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be. In a roundtable discussion with the Kavli Foundation, citizen science leaders and astrophysicists Chris Lintott, Anupreeta More and Aprajita Verma discuss the tremendous impact these enthusiastic volunteers are having.

Signs of second largest black hole in the Milky Way

Astronomers using the Nobeyama 45-m Radio Telescope have detected signs of an invisible black hole with a mass of 100 thousand times the mass of the Sun around the center of the Milky Way. The team assumes that this possible ‘intermediate mass’ black hole is a key to understanding the birth of the supermassive black holes located in the centers of galaxies.

Much like white light, spacetime is also composed of a certain rainbow

When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists have shown that in models of the Universe using any of the quantum theories of gravity there must also be a ‘rainbow’ of sorts, composed of different versions of spacetime. The mechanism predicts that instead of a single, common spacetime, particles of different energies essentially sense slightly modified versions thereof.

First light for future black hole probe

Zooming in on black holes is the main mission for the newly installed instrument GRAVITY at ESO’s Very Large Telescope in Chile. During its first observations, GRAVITY successfully combined starlight using all four Auxiliary Telescopes. During its initial tests, the instrument has already achieved a number of notable firsts. This is the most powerful VLT Interferometer instrument yet installed.

Runaway stars leave infrared waves

Astronomers have discovered roughly 100 of the fastest-moving stars in the Milky Way galaxy with the aid of images from NASA’s Spitzer Space Telescope and Wide-field Infrared Survey Explorer, and use of the Wyoming Infrared Observatory on Jelm Mountain near Laramie, Wyo.
