Astronomers find closest black hole to Earth

Astronomers find closest black hole to Earth

There’s a black hole lurking nearby, apparently, but you can breathe easy: It’s not a threat to Earth.  Astronomers believe they have found the closest black hole to our solar system, just 1,000 light years away, which in astronomical terms is right in our neighbourhood. The black hole — which is roughly four times the mass of […]

Study: Earth Formed Much Faster Than Previously Thought

Study: Earth Formed Much Faster Than Previously Thought

The precursor of our planet, the proto-Earth, formed within a time span of approximately five million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University of Copenhagen. On an astronomical scale, this is extremely fast, the researchers explain. If you compare the solar […]

How to view Jupiter at its closest to Earth over the next few days

How to view Jupiter at its closest to Earth over the next few days

If you want to check out the solar system’s largest planet, the next few nights are the best nights of the year to do it. On Monday night, Jupiter will reach opposition, meaning it will be directly opposite the sun and roughly 640,962,549 kilometres from Earth. Opposition also means that over the next few nights, the […]

Geologist who discovered oldest water on Earth wins top science award

Geologist who discovered oldest water on Earth wins top science award

Because she studies ancient water on Earth, Barbara Sherwood Lollar is usually looking down, but her work is also making her look to the stars. Sherwood Lollar, an earth sciences professor at the University of Toronto, has won the prestigious Gerhard Herzberg Canada Gold Medal for Science and Engineering for her work on ancient Earth […]

Brightest comet of the year can be seen as it zips past Earth

Brightest comet of the year can be seen as it zips past Earth

If you have clear skies and are willing to brave the chilly temperatures, you might want to head to a dark site and look for a passing visitor. Comet 46P/Wirtanen, first discovered in 1948, will have its closest encounter with Earth on Dec.16. But it’s already visible in the sky. While this is the brightest […]

Oldest fossils on Earth? New look finds they might just be rocks

Oldest fossils on Earth? New look finds they might just be rocks

What were billed as the oldest fossils on Earth may just be some rocks, according to a new study. Two years ago, a team of Australian scientists found odd structures in Greenland that they said were partly leftovers from microbes that lived on an ancient sea floor. They were said to be 3.7 billion years […]

How new telescope technology captured this image of Neptune from down here on Earth

How new telescope technology captured this image of Neptune from down here on Earth

It’s big, cold, blue and 4.3 billion kilometres away. But astronomers using cutting-edge optics technology have taken an image of Neptune that is nearly as sharp as those taken from the orbiting Hubble Space Telescope. The European Southern Observatory’s Very Large Telescope (VLT), nestled in the mountains of Chile’s Atacama Desert, was recently outfitted with a new type of adaptive […]

Over a billion people struggle to stay cool as Earth warms

Over a billion people struggle to stay cool as Earth warms

More than a billion people are at risk from a lack of air conditioning and refrigeration to keep them cool and to preserve food and medicines as global warming brings more high temperatures, a study showed on Monday. More electricity demand for fridges, fans and other appliances will add to man-made climate change unless power […]
