Space Astronomy

Construction has started on Canada’s largest radio telescope, the first to be built in more than three decades.

Supersonic geysers of charged particles have been discovered streaming from our galaxy’s center that span about two-thirds of the sky when viewed from Earth.

A new program called Skynet Junior Scholars will involve middle school students in astronomy with the hopes of fostering interested toward STEM subjects.

Stellar fireworks display for Guy Fawkes Night, celebrated on Nov. 5.

The Hubble Space Telescope (HST) has directly observed a luminous disc of matter being sucked into a supermassive black hole at the heart of a remote galaxy.

The brightest ever pulsar has been found inside a globular cluster of galaxies, comprising thousands or perhaps millions of stars held together by mutual gravity, orbiting our own Milky Way galaxy.

Gamma ray bursts (GRBs), the brightest explosions in the universe, can reveal information about our young universe, and may also fuel star formation.

High-speed crashes between asteroids and planets may be responsible for doughnut-shaped dust clouds that veil about 50 percent of known supermassive black holes.

A compact group of five galaxies has been snapped in new three-dimensional images to reveal different types of intergalactic star formation.

This image from the Wide-field Infrared Survey Explorer (WISE) shows the “Pacman” nebula seemingly chomping through space with teeth-like columns of dust and gas.

When faraway Eris blocked the light of a star beyond it during a rare occultation event in November 2010, astronomers were able to accurately measure the shape and size of this dwarf planet, which was identified as a large object in our solar system in 2005.

An ancient celestial event observed by Chinese astronomers almost two millennia ago has been explained using NASA’s Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE).

The mysterious nature of dark matter has deepened further with a new study that shows it is uniformly distributed across several hundred light-years in two nearby dwarf galaxies—the Fornax and the Sculptor.

This video shows how we actually measure a year on Earth. Since our planet’s orbit around the sun does not follow a perfect circle, it does not return to its starting point in space after one year.

A watery haze has been spotted in in a young star’s disk which extends almost 200 times the distance between Earth and the sun, according to new findings published in Science on Oct. 21.

Stargazers in both the Northern and Southern hemispheres could be treated to a lovely light show over the coming nights as the 2011 Orionid meteor shower enters its most active phase.
