We're One Step Closer To Uncovering Secrets Of Ancient 'Centaur' Comets

Comets are a frequent and gorgeous occurrence in outer space, and a study recently outlined plans for how scientists could watch them be created in real-time. As it's been proven time and time again, the mysteries of space are continually fascinating. Planets in our Solar System have many stories to tell, faraway galaxies hold countless other secrets, and there's a constant drive in the science community to uncover as many of these as possible. Thanks to constantly advancing technology, each...

A better understanding of space -- via helicopter

An algorithm that helps engineers design better helicopters may help astronomers more precisely envision the formation of planets and galaxies. Yale researchers Darryl Seligman and Greg Laughlin have created a new model for understanding how black holes, planets, and galaxies emerge from the vortex-rich environments of space.

To watch a comet form, a spacecraft could tag along for a journey toward the sun

Deep in the solar system, between Jupiter and Neptune, lurk thousands of small chunks of ice and rock. Occasionally, one of them will bump into Jupiter’s orbit, get caught and flung into the inner solar system—towards the sun, and us. This is thought to be the source of many of the comets that eventually pass Earth. A new study lays out the dynamics of this little-understood system. Among the findings: it would be doable for a spacecraft to fly to Jupiter, wait in Jupiter’s orbit until one of th...

Mysterious interstellar visitor was probably a ‘dark hydrogen iceberg,’ not aliens

The aliens came on Oct. 19, 2017. That was the day telescopes picked up a strange object with an odd, elongated shape that moved like a comet—but had no apparent tail. The object, which baffled astronomers and led some to claim it could be a spacecraft sent by intelligent life, was named ‘Oumuamua, which means “messenger from afar arriving first” in Hawaiian. But a new theory proposed by University of Chicago and Yale astronomers explains the phenomenon without aliens—but with interesting scient...
