Join the Live Discussion: The Hunt for Other Worlds Heats Up

As readers of Universe Today know, exoplanets are one of the hottest topics in astronomy today. In just the past six months, astronomers have announced the discovery of more than 700 planets orbiting other stars, bringing the total to more than 1700. These discoveries include the first Earth-size planet found in what’s called the habitable …

Nearby Super-Earth is Best Habitable Candidate So Far, Astronomers Say

On a clear night, you might be able to spot the red dwarf star Gliese 832 through a backyard telescope, as it is just 16 light years away. Today, astronomers announced the discovery of super-Earth planet orbiting this nearby star and say it might be the best candidate yet for habitable world. Gliese 832c was …

Kepler Has Found the First Earth-Sized Exoplanet in a Habitable Zone!

It’s truly a “eureka” moment for Kepler scientists: the first rocky Earth-sized world has been found in a star’s habitable “Goldilocks” zone, the narrow belt where liquid water could readily exist on a planet’s surface without freezing solid or boiling away. And while it’s much too soon to tell if this really is a “twin …

Ceres and Vesta Converge in Virgo, Watch it Happen With Just Binoculars

Don’t let them pass you by. Right now and continuing through July, the biggest and brightest asteroids will be running on nearly parallel tracks in the constellation Virgo and so close together they’ll easily fit in the same binocular field of view.  The twofer features Ceres (biggest) and Vesta (brightest) which are also the prime …

50 Years of Talking to Space: a NASA Social for the Deep Space Network

When you’re talking to spacecraft billions of miles away, you need a powerful voice. And when you’re listening for their faint replies from those same staggering distances, you need an even bigger set of ears. Fortunately, NASA’s Deep Space Network has both — and last week I had the chance to see some of them up close …

Discovery! Possible Dwarf Planet Found Far Beyond Pluto’s Orbit

What is a dwarf planet? Some astronomers have been asking that question after Pluto was demoted from planethood almost a decade ago, partly due to discoveries of other worlds of similar proportions. Today, astronomers announced the discovery of 2012 VP113, a world that, assuming its reflectivity is moderate, is 280 miles (450 kilometers) in size and orbiting …

Asteroid Swarm ‘Pounded’ Pulsar Star, Causing Changes Visible From Earth

When you throw a bunch of rock and debris at a rapidly spinning star, what happens? A new study suggests that so-called pulsar stars change their dizzying spin rate as asteroids fall into the gaseous mass. This conclusion comes from observations of one pulsar (PSR J0738-4042) that is being “pounded” with debris from rocks, researchers …

Search for Planetary Nurseries in the Latest Citizen Science Project

Growing up, my sister played video games and I read books. Now that she has a one-year-old daughter we constantly argue over how her little girl should spend her time. Should she read books in order to increase her vocabulary and stretch her imagination? Or should she play video games in order to strengthen her …
