NASA's Hubble Space Telescope spots Mars-bound comet sprout multiple jets

How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA's Wide-field Infrared Survey Explorer, or WISE, has turned up what might be the cosmic seeds from which a black hole will sprout. The results are helping scientists piece together the evolution of supermassive black holes -- powerful objects that dominate the hearts of all galaxies.

2014 is a good year to find a comet

A team of European astronomers has found a previously unknown comet, detected as a tiny blob of light orbiting our Sun deep in the Solar System. Europe’s Teide Observatory Tenerife Asteroid Survey team has been credited with discovering comet P/2014 C1, named ‘TOTAS’ in recognition of the teamwork involved in the find.

Standing on a comet

A comet-bound spacecraft that spent more than two years in a deep sleep mode woke up on Jan. 20 to begin the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice. Rosetta—a European Space Agency-led mission that involves University of Michigan engineers and scientists—is on track to be the first craft to actually land on a comet as well as track it for an extended period of time.

Space droids battle to save Earth from comet

A comet heading towards Earth threatens humanity’s existence – that was the virtual scenario of this year’s Zero Robotics tournament. Secondary-school students from across Europe controlled miniature satellites on the International Space Station in a competition to save our planet.

How to cook a comet

A comet's journey through the solar system is perilous and violent. A giant ejection of solar material from the sun could rip its tail off. Before it reaches Mars -- at some 230 million miles away from the sun -- the radiation of the sun begins to boil its water, the first step toward breaking the comet apart.

When is a comet not a comet?

Astronomers using the NASA/ESA Hubble Space Telescope have observed a unique and baffling object in the asteroid belt that looks like a rotating lawn sprinkler or badminton shuttlecock. While this object is on an asteroid-like orbit, it looks like a comet, and is sending out tails of dust into space.

NASA's Hubble sees Comet ISON intact

A new image of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it. The comet will pass closest to the sun on Nov. 28.

First ever evidence of a comet striking Earth

The first ever evidence of a comet entering Earth's atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered by a team of South African scientists and international collaborators.

This comet was hidden in plain sight

For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists while keeping something to itself: 3552 Don Quixote, whose journey stretches to the orbit of Jupiter, now appears to be a comet.  

Claim: Comet, not an asteroid, killed the dinosaurs

In a key geological moment about 66 million years ago, an enigmatic something killed off almost all the dinosaurs and some 70 percent of all other species living on Earth.

How to spot comet Pan-STARRS this weekend

The brightest comet for several years should become visible in the Northern Hemisphere night sky over the next few days.

Outside chance of comet hitting Mars next year

A recently-discovered comet has a chance - albeit a small one - of hitting Mars in October next year.

New dates support impact theory of dinosaur extinction

Scientists say they're homing in on the precise date of both the extinction of the dinosaurs 66 million years ago, and the massive impact that's believed by many to have caused it.

Comet not responsible for Clovis disappearance

A group of researchers has poured scorn on the idea that a comet wiped out the North American Clovis people 13,000 years ago.

Approaching comet may be brightest in a century

A newly-discovered comet looks likely to blaze brightly in our skies late next year.

Did comet wipe out Clovis culture?

More evidence has emerged that a massive comet hit the Earth about 13,000 years ago, backing up a widely-disputed theory.

Evidence found for huge asteroid strike

Scientists say they've found more evidence of a major impact by a comet or asteroid, some 13,000 years ago.
