This artist's conception shows the closest known planetary system to our own, called Epsilon Eridani. Observations from NASA's Spitzer Space Telescope show that the system hosts two asteroid belts, in addition to previously identified candidate planets and an outer comet ring. Epsilon Eridani is located about 10 light-years away in the constellation Eridanus. It is visible in the night skies with the naked eye. The system's inner asteroid belt appears as the yellowish ring around the star, while the outer asteroid belt is in the foreground. The outermost comet ring is too far out to be seen in this view, but comets originating from it are shown in the upper right corner. Astronomers think that each of Epsilon Eridani's asteroid belts could have a planet orbiting just outside it, shepherding its rocky debris into a ring in the same way that Jupiter helps keep our asteroid belt confined. The planet near the inner belt was previously identified in 2000 via the radial velocity, or

Is this Solar System 2.0?

THERE’S something odd about our Solar System. We’ve found some 470 stars with planets around them. But it’s only now that we’ve spotted one that looks anything like our own.

This NASA handout image released July 20, 2015 shows Earth as seen on July 6, 2015 from a distance of one million miles captured by a NASA scientific camera aboard the Deep Space Climate Observatory spacecraft. The color images of Earth from NASA’s Earth Polychromatic Imaging Camera (EPIC) were generated by combining three separate images to create a photographic-quality image. The camera takes a series of 10 images using different narrowband filters -- from ultraviolet to near infrared -- to produce a variety of science products. The red, green and blue channel images are used in these Earth images. AFP PHOTO / NASA / HANDOUT == RESTRICTED TO EDITORIAL USE / MANDATORY CREDIT:

NINE years of nervous tension certainly builds up. While the New Horizons probe sailed past Pluto, the world’s astronomers were biting fingernails and letting off steam on Twitter.

Probe survives Pluto flyby

THE New Horizons space probe has survived its close shave with Pluto, sharing a brief burst of self-diagnostics with NASA as it starts to sift through the mass of data it has gathered.

‘Pyramid’ added to Ceres mysteries

FAILED planet Ceres just keeps getting stranger: Not only are we still no closer to understand its strange lights, NASA’s just spotted a 5km tall ‘pyramid’ jutting out of the dust.

Is this proof of alien life?

A CLUSTER of bright, white spots on the surface of a distant dwarf planet has left experts scratching their heads. Is it a sign of life?

***SUNDAY CALENDAR SNEAKS STORY FOR NOVEMBER 2, 2014. DO NOT USE PRIOR TO PUBLICATION********* From the movie INTERSTELLAR, from Paramount Pictures and Warner Brothers Entertainment. FROM CHRISTOPHER NOLAN. The look of our black hole was based on real science; equations given to our visual effects team by Kip Thorne, our executive producer, that define exactly how the black hole's gravity would warp space-time and bend light to create the otherworldly image. Their collaboration yielded great imagery and actually furthered the science of black hole research.

Are we wrong about black holes?

THEY may be black. But are they holes? It seems we may have got the universe’s most awesome phenomenon wrong: Are they instead giant fuzzy photocopiers?
