This image shows free-air gravitational anomalies and a shaded topographic relief of the Moon’s 930-km-diameter Orientale impact basin. Red corresponds to mass excesses and blue to mass deficits relative to a reference value. This gravitational field model, based on measurements acquired from the NASA GRAIL mission, shows the detailed structure of the central basin depression that is filled with...

In the year since New Horizons flew past Pluto, scientists have discovered intriguing details about the dwarf planet's atmosphere. Seen here, haze particles form numerous intricate, horizontal layers, some extending for hundreds of miles around Pluto. The haze layers extend to altitudes of over 120 miles (200 kilometers).

3 Questions: Richard Binzel on what we've learned so far from New Horizons

This illustration depicts the view from outside of a rapidly-accreting black hole. The bright light toward the center represents the super-heating of gas as it falls onto the black hole. Emanating from the center is a jet of accelerated particles moving near the speed of light. Surrounding the black hold is cool, clumpy gas and dust, which are falling inwards and will eventually join the material ...

Scientists observe supermassive black hole feeding on cold gas

Findings suggest two dining styles for black holes.

MIT scientists say that the Great Oxygenation Event (GOE), a period that scientists believe marked the beginning of oxygen’s permanent presence in the atmosphere, started as early as 2.33 billion years ago.

Study pinpoints timing of oxygen’s first appearance in Earth’s atmosphere

Beginning 2.33 billion years ago, atmospheric oxygen built up in just 10 million years.

This artist’s rendering shows an imagined view of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO’s La Silla Observatory. In this view, one of the inner planets is seen in transit across the disc of its tiny and dim parent star.

Scientists discover potentially habitable planets

Just 40 light years from Earth, planets are best targets so far for search for extraterrestrial life.

This artist’s rendering shows the super-Earth 55 Cancri e in front of its parent star. The planet is essentially a heat-seeking fireball, orbiting extremely close to its star. It circles in just 18 hours, compared to Earth’s leisurely 365-day journey around the sun.

An artist’s rendering of a protoplanetary impact. Early in the impact, molten jetted material is ejected at a high velocity and breaks up to form chondrules, the millimeter-scale, formerly molten droplets found in most meteorites. These droplets cool and solidify over hours to days.

A twist on planetary origins

New study finds meteorites were byproducts of planetary formation, not building blocks.
