2I/Borisov is the first interstellar comet seen, and Hubble has been watching its journey through our neighborhood. The telescope has snapped new images of the comet, which has now swung past the Sun and is on its way back out of the solar system.

NASA has made its final selection of the site on asteroid Bennu where the agency's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-Rex) deep space probe will collect a sample for return to Earth.

Intended as a potential aid to future space travelers, NASA has released a water map of Mars. Based on remote sensing data from the space agency's Mars orbiters, the new map shows areas where water ice may lurk within an inch (2.5 cm) of the surface.

A new study from Northwestern University is demonstrating evidence a novel implantable ultrasound device allows a less toxic formulation of chemotherapy to cross the blood-brain barrier and destroy deadly tumors.

Researchers at Rice University have developed a new method to kill emerging superbugs, using molecular “drills” to pierce their cell walls. The same technique has also been shown to work on cancer cells.

It hasn’t been entirely smooth sailing, but The Ocean Cleanup is now calling an end to a first successful mission to collect plastic from the Great Pacific Garbage Patch, today showing off the first pile of captured trash on the shores of Vancouver.

Although breathalyzers have been used to check drivers' blood alcohol levels for decades now, the things do have their drawbacks. In the near future, however, police officers and others may get better results using a simple strip-type test kit.

The ancestors of today's whales originally walked on four legs. New research suggests that previously-discovered fossils represent a point at which the creatures were moving from swimming with those legs to swimming with their tails.

ESA's Mars Express spacecraft has captured a rare movie of the Martian moon Phobos. The moon is set to be the target of an international mission to survey the Red Planet’s two natural satellites, and return a surface sample to Earth.

Scientists in Korea believe they’ve found a way around the opaque nature of conventional solar cells, with a new technique that involves punching carefully placed holes right through them to make them transparent.

A comprehensive new study has tracked long-term ice loss in Greenland, and found that the Ice Sheet has lost 3.8 trillion tonnes of ice since 1992 – and the annual rate is rising faster than previously expected.

Blue Origin's New Shepard booster completed its 12th successful test flight on December 11, marking the first time a booster has made six consecutive missions. At 11:53 am CDT, the single-stage rocket lifted off for a 10 min 16 sec flight.
