Gravitational waves caught again

The second detection of gravitational waves from merging black holes is a significant milestone in the development of physics. Scientists have found that the observed gravity waves were generated by two black holes with masses of 14 and 8 solar masses, which merged to form a single rotating black hole.

Writing their name in the stars: Citizen scientists discover huge galaxy cluster

Two volunteer participants in Radio Galaxy Zoo discovered a rare C-shaped galaxy cluster that they pieced together from much smaller images of cosmic radio waves. The team's dataset, with over 1.6 million images classified by 10,000 volunteers, has already reached almost 60% completeness.

A new way to nip AIDS in the bud

Scientists at the University of Utah found that delaying the budding of new HIV particles triggers protease to destroy the virus, rendering it non-infectious. This breakthrough could lead to the development of new AIDS treatments with fewer side effects in about a decade.

New research shows quasars slowed star formation

A team of astronomers has found evidence that quasars' energy feedback may have slowed down star formation in the universe about 11 billion years ago. The study used data from multiple telescopes to detect the Sunyaev-Zel'dovich Effect, a phenomenon caused by high-energy electrons disturbing the Cosmic Microwave Background.

Longest-lasting stellar eclipse discovered

Astronomers have discovered a binary star system with the longest duration stellar eclipse, lasting three and a half years, and the longest period between eclipses in a binary system. The system, TYC 2505-672-1, is approximately 20 astronomical units from Earth and consists of two red giant stars.

Quiet quasar has apparently eaten its fill

Astronomers discovered a distant quasar that has apparently run out of gas, leading to a significant decrease in its brightness. The quasar, SDSS J1011+5442, was found to have consumed all the glowing-hot gas in its vicinity, causing it to dim drastically.
