Its science program committee just approved the Laser Interferometer Space Antenna—affectionately known as LISA—for official planning and building. That means gravitational wave astronomers ...

The Laser Interferometer Space Antenna (LISA) mission, which consists of three spacecraft that together form a single gravitational wave detector, is a collaboration between NASA and the European ...

Strange x-ray pulses hint at a surprisingly long-lived white dwarf orbiting precariously close to a supermassive black hole ...

For half a century, astrophysicists have been trying to solve the Black Hole Information Paradox—first explained by Stephen Hawking in 1976—which posits that black holes destroy information. That ...

Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be coming from a white dwarf - a ...

Instruments designed for this purpose, like the Laser Interferometer Space Antenna (LISA), require highly sensitive test masses that can detect minute changes in gravitational forces. However ...

In this artist’s concept, matter is stripped from a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. Astronomers ...

One significant area of research involves the charging of test masses used in gravitational wave detection missions, such as the Laser Interferometer Space Antenna (LISA). Studies have shown that ...

The size and spin of black holes can reveal how and where they were born, and gravitational waves offer a way to decode this ...

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.
