Astronomers Think a Meteor Came from Outside the Solar System When ‘Oumuamua was first detected on October 19th, 2017, astronomers were understandably confused about the nature of this strange object. Initially thought to be an interstellar comet, it was then designated as an interstellar asteroid. But when it picked up velocity as it departed our Solar System (a very comet-like thing to do), scientists could … Continue reading “Astronomers Think a Meteor Came from Outside the Solar System” The post Astronomers Think a Meteor Came from Outside the Solar System appeared first on Universe Today.

Barfing Neutron Stars Reveal Their Inner Guts We don’t really understand neutron stars. Oh, we know that they are – they’re the leftover remnants of some of the most massive stars in the universe – but revealing their inner workings is a little bit tricky, because the physics keeping them alive is only poorly understood. But every once in a while two … Continue reading “Barfing Neutron Stars Reveal Their Inner Guts” The post Barfing Neutron Stars Reveal Their Inner Guts appeared first on Universe Today.

What Will the James Webb Space Telescope See? A Whole Bunch of Dust, That’s What When it comes to the first galaxies, the James Webb Space Telescope will attempt to understand the formation of those galaxies and their link to the underlying dark matter. In case you didn’t know, most of the matter in our universe is invisible (a.k.a. “dark”), but its gravity binds everything together, including galaxies. So by … Continue reading “What Will the James Webb Space Telescope See? A Whole Bunch of Dust, That’s What” The post What Will the James Webb Space Telescope See?

The First Molecule that was Possible in the Universe has been Seen in Space It takes a rich and diverse set of complex molecules for things like stars, galaxies, planets and lifeforms like us to exist. But before humans and all the complex molecules we’re made of could exist, there had to be that first primordial molecule that started a long chain of chemical events that led to everything … Continue reading “The First Molecule that was Possible in the Universe has been Seen in Space” The post The First Molecule that was Possible in the Universe has been Seen in Space appeared first onRead More →

TESS Just Found its First Earth-Sized World NASA’s new planet-hunting telescope, TESS (Transiting Exoplanet Survey Satellite), just found its first Earth-sized world. Though the Earth-sized planet, and its hot sub-Neptune companion, were first observed by TESS in January 2019, it’s taken until now to confirm their status with ground-based follow-up observations. The discovery is published in The Astrophysical Journal Letters. When TESS … Continue reading “TESS Just Found its First Earth-Sized World” The post TESS Just Found its First Earth-Sized World appeared first on Universe Today.

Astro-Challenge: Spotting Slender Moons Up for a challenge? Some of the toughest targets for a backyard observer involve little or no equipment at all. Northern hemisphere Spring brings with it one of our favorite astronomical pursuits: the first sighting of the extremely thin, waxing crescent Moon. This unique feat of visual athletics may be fairly straight forward… but it’s tougher than you think. The angle of the evening ecliptic in the Spring is still fairly high for mid-northern latitudes, taking the Moon up and out of the weeds as a waxing crescent.
