Later this year, Comet ISON is expected to become a naked-eye object when it skims through the atmosphere of the sun. The Hubble Space Telescope has just obtained a sneak preview.

Hubble photographed ISON on April 10th. At the time, the comet was 386 million miles from the sun (394 million miles from Earth), just inside the orbit of Jupiter. …

A patchwork network of frozen ridges and troughs cover the face of Enceladus, Saturn’s most enigmatic of icy moons.

This face-on colour view of Enceladus was taken by the international Cassini spacecraft on 31 January 2011, from a distance of 81 000 km, and processed by amateur astronomer Gordan Ugarković.

Anticipation is building as Comet ISON plunges into the inner solar system for a close encounter with the sun in November 2013. Blasted at point-blank range by solar radiation, the sungrazer will likely become one of the finest comets in many years.

When NASA’s Swift spacecraft observed the comet in January 2013, it was still near the orbit of Jupiter, …

For hand towels, astronauts get those little vacuum-packed pucks that you kind of have to unravel into a towel. But what happens when you actually put the towels to use?

Two Nova Scotia high school students, Kendra Lemke and Meredith Faulkner, submitted this experiment to Canadian Space Agency and got to see astronaut Chris Hadfield actually test it out on …

NASA’s Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the “habitable zone,” the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.


The artist’s concept depicts Kepler-62f, a super-Earth-size planet in the habitable zone of a star smaller and cooler than the sun, …
