Saturn’s Rings are Only 10 to 100 Million Years Old

Saturn’s Rings are Only 10 to 100 Million Years Old Can you imagine the Solar System without Saturn’s rings? Can you envision Earth at the time the dinosaurs roamed the planet? According to a new paper, the two may have coincided. Data from the Cassini mission shows that Saturn’s rings may be only 10 to […]

Milky Way’s neighbors pick up the pace

Milky Way’s neighbors pick up the pace After slowly forming stars for the first few billion years of their lives, the Magellanic Clouds, near neighbors of our own Milky Way galaxy, have upped their game and are now forming new stars at a fast clip. This new insight into the history of the Clouds comes […]

A Fleeting Moment in Time

A Fleeting Moment in Time The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time — around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas — the last breath of the dying star whose simmering […]

Astronomy Cast Ep. 514: Planetary Protection Protocols

Astronomy Cast Ep. 514: Planetary Protection Protocols As we send rovers and landers to other worlds, we have to think about the tiny microbial astronauts we’re sending along with us. In fact, NASA is so concerned about infecting other worlds that it has established the planetary protection protocols. Just to be safe. We usually record […]

How hot are atoms in the shock wave of an exploding star?

How hot are atoms in the shock wave of an exploding star? A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion. An international team of researchers, including a Penn State scientist, combined […]

Steam-Powered Spacecraft Could Explore the Asteroid Belt Forever, Refueling Itself in Space

Steam-Powered Spacecraft Could Explore the Asteroid Belt Forever, Refueling Itself in Space A partnership between Honeybee Robotics and the University of Central Florida has produced the first steam-powered spacecraft for asteroid mining.

The disintegrating exoplanet K2-22b

The disintegrating exoplanet K2-22b Exoplanet surveys have yielded many surprises over the years, and the discovery of “disintegrating” exoplanets was one of them. These are planets that produce asymmetric shapes in the dips of the light curves seen as they transit across the faces of their stars. The asymmetry is hypothesized to be due to […]

New eclipsing cataclysmic variable discovered

New eclipsing cataclysmic variable discovered Using the Mobile Astronomical System of Telescope-Robots (MASTER), an international team of astronomers has detected a new eclipsing cataclysmic variable. The newfound object, designated MASTER OT J061451.70–272535.5, is most likely of the polar subclass. The finding is detailed in a paper published January 9 on arXiv.org. phys.org Go to Source

Seeding the Milky Way with Life Using Genesis Missions

Seeding the Milky Way with Life Using Genesis Missions Claudius Gros, the founder of Project Genesis, makes the case that when it comes to extrasolar planets, the rules of planetary protection need not apply.

Cassini Saw Rain Falling at Titan’s North Pole

Cassini Saw Rain Falling at Titan’s North Pole The Cassini mission to Saturn ended in September 2017, but the data it gathered during its 13 year mission is still yielding scientific results. On the heels of a newly-released global image of Saturn’s moon Titan comes another discovery: Rainfall at Titan’s north pole. Climate models developed […]

Making stars when the universe was half its age

Making stars when the universe was half its age The universe is about 13.8 billion years old, and its stars are arguably its most momentous handiwork. Astronomers studying the intricacies of star formation across cosmic time are trying to understand whether stars and the processes that produce them were the same when the universe was […]
