A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

Scientists have long believed that the Moon was formed by a massive object crashing into the Earth. But what was that thing ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

Intermediate mass black holes (IMBH), if they exist, have between about 100 and 1,000 solar masses, placing them in between ...

Four UC Nobel laureates on what they discovered here, why it matters, and why their world-changing work could only have ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including ...

New gravitational lensing measurements by the TDCOSMO Collaboration support the Hubble Tension, confirming differences between Early and Late Universe Hubble Constant values using updated ...
