B612 Asteroid Institute provides valuable analysis to discovery of First Interstellar Object

Within days of the announcement by NASA’s Minor Planet Center of the discovery of the first-ever interstellar object, ‘Oumuamua, B612’s new Asteroid Institute began a collaborative effort that led to significant analysis about the discovery.

Bryce Bolin, a senior researcher at the Asteroid Institute as well as a DIRAC Institute Fellow,

A Familiar-Looking Messenger from another Solar System

The visit of the interstellar interloper 1I/2017 U1, recently spotted streaking through the Solar System, gives the people of Earth their first chance to study up close an object from another planetary system. In a study carried out with the WIYN telescope at Kitt Peak National Observatory and the Nordic Optical Telescope in the Canary Islands,

Unlucky dinosaurs: Scientists say asteroid had 13 percent chance of triggering extinction

When an asteroid came barreling into Earth some 66 million years ago, it wasn’t necessarily a guarantee that life on planet Earth would be drastically altered — that 75 percent of all plant and animal species, including the dinosaurs, would disappear.

According to a new study published Thursday in the journal Scientific Reports,

Astronomers Complete First International Asteroid Tracking Exercise

An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.

Planning for the so-called “TC4 Observation Campaign” started in April, under the sponsorship of NASA’s Planetary Defense Coordination Office. The exercise commenced in earnest in late July,

Dinosaur-killing asteroid impact cooled Earth’s climate more than previously thought

The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to new research.

A new study makes a more refined estimate of how much sulfur and carbon dioxide gas were ejected into Earth’s atmosphere from vaporized rocks immediately after the Chicxulub event.

Has the First Interstellar Comet Been Discovered?

Astronomers from the Minor Planet Center sent out an announcement today, hoping for astronomers to do followup observations on the comet C/2017 U1 PANSTARRS. That’s because this strange comet seems to be on a trajectory that originated outside our Solar System. Not just from the Oort Cloud, but from another star.

Astronomers Spot First-Known Interstellar Comet

By: Kelly Beatty

For centuries, skywatchers have chronicled the comings and goings of thousands of comets. Every one of them has come from someplace in our own solar system, either the Kuiper Belt beyond Neptune or the much more distant Oort Cloud at the fringes of the Sun’s realm.

Spinning comet rapidly slows down during close approach to Earth

Astronomers at Lowell Observatory observed comet 41P/Tuttle-Giacobini- Kresak last spring and noticed that the speed of its rotation was quickly slowing down. A research team led by David Schleicher studied the comet while it was closer to the Earth than it has ever been since its discovery. The comet rotational period became twice as long,

A solar-powered asteroid nursery at the orbit of Mars

The planet Mars shares its orbit with a handful of small asteroids, the so-called Trojans. Among them, one finds a unique group, all moving in very similar orbits, suggesting that they originated from the same object. But the mechanism that produced this “family” has been a mystery.

Now,

Samples brought back from asteroid reveal ‘rubble pile’ had a violent past

Curtin University planetary scientists have shed some light on the evolution of asteroids, which may help prevent future collisions of an incoming ‘rubble pile’ asteroid with Earth.

The scientists studied two incredibly small particles brought back to Earth from the asteroid Itokawa, after they were collected in 2005 from the surface of the 500 metre-wide asteroid,
