While astronomers didn’t bag that elusive first “alien Earth” in 2013, they made plenty of exciting exoplanet discoveries during the past year.
Here’s a list of the top exoplanet finds of 2013, from a tiny world about the size of Earth’s moon to a blue gas giant on which it rains molten glass:
The smallest exoplanet
In February, astronomers announced the discovery of Kepler-37b, the smallest alien world ever found around a sun-like star. The planet is about 2,400 miles (3,900 kilometers) wide, making it just slightly larger than Earth’s moon.

Habitable alien planets similar to Earth may not be that rare in the universe, a new study suggests.
About one in five sunlike stars observed by NASA’s planet-hunting Kepler spacecraft has an Earth-size planet in the so-called habitable zone, where liquid water — and, potentially life — could exist, according to the new study. If these results apply elsewhere in the galaxy, the nearest such planet could be just 12 light-years away.
“Human beings have been looking at the stars for thousands of years,” said study researcher Erik Petigura, a graduate student at the University of California, Berkeley (UC Berkeley). “How many of those stars have planets that are in some way like Earth? We’re very excited today to start to answer that question,” Petigura told SPACE.com. [9 Exoplanets That Could Host Alien Life]

NASA can prove it now. Our solar system has a tail, just like comets.
Scientists revealed images Wednesday showing the tail emanating from the bullet-shaped region of space under the grip of the sun, including the solar system and beyond. The region is known as the heliosphere, thus the name heliotail.
The findings are based on data from by NASA’s Interstellar Boundary Explorer, or IBEX. The Earth-orbiting spacecraft was launched in 2008.
Scientists always presumed the heliosphere had a tail, but this provides the first real data on the shape.

The habitable zone of a nearby star is filled to the brim with planets that could support alien life, scientists announced today (June 25).
An international team of scientists found a record-breaking three potentially habitable planets around the star Gliese 667C, a star 22 light-years from Earth that is orbited by at least six planets, and possibly as many as seven, researchers said. The three planet contenders for alien life are in the star’s “habitable zone” — the temperature region around the star where liquid water could exist. Gliese 667C is part of a three-star system, so the planets could see three suns in their daytime skies.
The three potentially rocky planets in Gliese 667C’s habitable zone are known as super-Earths — exoplanets that are less massive than Neptune but more massive than Earth. Their orbits make them possible candidates for hosting life, officials from the European Southern Observatory said in a statement.

Smooth, round pebbles found by NASA’s Mars rover Curiosity provide more evidence that water once flowed on the Red Planet, according to a new study.
The Curiosity rover snapped pictures of several areas with densely packed pebbles, and by closely analyzing the rock images, researchers discovered that the shapes and sizes of the individual pebbles indicate that they traveled long distances in water, likely as part of an ancient riverbed.
The rocks were found near Curiosity’s landing site, between the north rim of Gale Crater and the base of Mount Sharp, a peak that rises 3 miles (5 kilometers) above the crater floor.
.
The Curiosity rover investigated an area on Mars named Hottah, which appears to be part of an ancient riverbed.

Scientists may have discovered the first meteorite from Mercury.
The green rock found in Morocco last year may be the first known visitor from the solar system’s innermost planet, according to meteorite scientist Anthony Irving, who unveiled the new findings this month at the 44th annual Lunar and Planetary Science Conference in The Woodlands, Texas. The study suggests that a space rock called NWA 7325 came from Mercury, and not an asteroid or Mars.
NWA 7325 is actually a group of 35 meteorite samples discovered in 2012 in Morocco. They are ancient, with Irving and his team dating the rocks to an age of about 4.56 billion years.

A sun-like star in our solar system’s backyard may host five planets, including one perhaps capable of supporting life as we know it, a new study reports.
Astronomers have detected five possible alien planets circling the star Tau Ceti, which is less than 12 light-years from Earth — a mere stone’s throw in the cosmic scheme of things. One of the newfound worlds appears to orbit in Tau Ceti’s habitable zone, a range of distances from a star where liquid water can exist on a planet’s surface.
With a minimum mass just 4.3 times that of Earth, this potential planet would be the smallest yet found in the habitable zone of a sun-like star if it’s confirmed, researchers said.

Tomorrow is the big day. Time to dust off your eclipse glasses, binoculars and posterboard, or pinhole camera and witness the transit of Venus, a once in a lifetime event! (Actually, it’s a twice in a lifetime event, but if you missed it eight years ago, this is your last chance!)
