Chinese space telescope to observe ‘big eaters’
China's new space telescope will probe many mysteries of the universe, including the belching "big eaters"-active galactic nuclei at the most remote edges of the universe. Scientists have discovered that almost every galaxy has a supermassive black hole with a mass several million to several billion times that of the Sun at its centre. With...

Rocket to take 1,500 images of Sun in five minutes: NASA
A sounding rocket, designed to take 1,500 images of the Sun in just five minutes from about 320 kilometres above the Earth's surface, is set to be launched on Friday, according to NASA. The Rapid Acquisition Imaging Spectrograph Experiment (RAISE) mission is designed to scrutinise split-second changes occurring near the Sun's active regions – areas...

Morocco’s Noor: Capturing the sun to bring light
Four years ago, Morocco imported 93 per cent of its energy needs. By 2030, it hopes to get 52 per cent from renewables. Just how serious the country is about solar power comes across loud and clear to visitors as soon as one crosses the Mohamed V International Airport here. Large solar panels along the...

How wrong-way asteroid avoids colliding with Jupiter
For at least a million years, an asteroid orbiting the "wrong" way around the Sun has been playing a cosmic game of chicken to avoid collision with Jupiter and with about 6,000 other asteroids sharing the giant planet's space, a study says. The findings published in the journal Nature showed that the orbit has been...

Earth-like planetary waves discovered around Sun
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, new research has found. Just as the large-scale waves that form on Earth, known as Rossby waves, influence local weather patterns, the waves discovered on the Sun may be intimately tied to solar...

Ants use sun, memories for ‘backward’ walk home
Ants, which are famed for their highly developed work ethic, use the sun and memories of their surroundings to find the way home when they walk backward dragging a heavy load, scientists have found. A study, published in the journal Current Biology, showed that ants' navigational skills are very sophisticated as when walking backward, they...

Dark sunspot centre spotted
A new view of the dark, contorted centre of a sunspot that is nearly twice the diameter of the Earth, along with other invisible details of our Sun, has been unveiled by scientists. The results are an important expansion of the range of observations that can be used to probe the physics of our nearest...
