NASA completes key review of world’s most powerful rocket in support of journey to Mars

NASA officials Wednesday announced they have completed a rigorous review of the Space Launch System (SLS) — the heavy-lift, exploration-class rocket under development to take humans beyond Earth orbit and to Mars — and approved the progra...

Radio telescopes settle controversy over distance to Pleiades

Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster — a controversy that posed a potential challenge to scientists’ basic understanding of how stars form and ev...

Telescopes uncover early construction of giant galaxy

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming ...

Detecting neutrinos, physicists look into the heart of the Sun

Using one of the most sensitive neutrino detectors on the planet, an international team of physicists, including Andrea Pocar, Laura Cadonati, and Keith Otis at the University of Massachusetts, Amherst, report that for the first time they have direct...

Eta Carinae: our neighboring superstars

The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, it also is extremely volatile and is expected to have at least ...

Fascinating rhythm: light pulses illuminate a rare black hole

The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big or colossal. Astronomers know...

As seen by Rosetta: comet surface variations

A new image of Comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus. It was taken by the Rosetta spacecraft's OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65 miles (104km) a...
