Millions of Americans will look up toward the sky on Monday and watch stars shine in the afternoon, feel the day’s heat swapped for an evening chill and hear the sounds of confused birds and animals during the first total eclipse seen in the continental US in 38 years.

The spectacular event will cross a strip of the country occupied by 12.2 million people, with millions more expected to travel to the 70-mile-wide eclipse path, aiming to catch a glimpse of a site that has captured the imaginations of people for millennia. ... See more

The Cassini probe has begun the final phase of its mission to Saturn. The satellite has executed the first of five ultra-close passes of the giant world, dipping down far enough to brush through the top of the atmosphere.

It promises unprecedented data on the chemical composition of Saturn. It also sets the stage for the probe's dramatic end-manoeuvre next month when it will plunge to destruction in the planet's atmosphere. ... See more

Cassini is on its final five full orbits of Saturn, getting close enough to directly "taste" its gases.

The annual Perseid meteor shower will fill the night sky with glowing streaks this weekend, as the Earth travels through debris shed by comet Swift-Tuttle.

The sturgeon full moon in partial eclipse - in pictures

August’s full moon, known as the sturgeon moon, featured a partial eclipse as it was slightly covered by the Earth’s shadow

An eclipse is the serendipitous alignment of the Earth, the Moon, and the Sun. Around every 18 months or so, the Moon passes directly between the Earth and the Sun on its orbit around our planet. It’s a relatively rare occurrence because the Moon doesn’t orbit in the same plane as the Earth and Sun. But when the three bodies line up just right, the Moon covers up the disc of the Sun, and those in the direct path of the Moon’s shadow — called the path of totality — will see the Sun go dark. ...

On August 21st, the Great American Eclipse will descend upon the United States, casting its shadow from coast to coast for the first time since 1918.

The GhanaSat-1―Ghana’s first satellite―built by a Ghanaian engineering team at All Nations University, was delivered to NASA’s International Space Station in June on a SpaceX rocket that took off from pad 39a at Kennedy Space Center, a NASA spokesperson confirmed.

The GhanaSat-1 deployed into orbit from the Center in July, and is now operational, according to project manager Richard Damoah, a Ghanaian professor and assistant research scientist at NASA. ... See more

China has used the Sunway TaihuLight, the world's most powerful supercomputer, to simulate "the birth and early expansion of the Universe" using 10 trillion digital particles.

The work has reportedly been completed by the National Supercomputer Centre in Wuxi, and involved computer scientists from the Chinese Academy of Sciences in Beijing. The supercomputer used 10 million CPU cores to create the universe – known as N-body simulation – and involved breaking the universe's mass down into particles. ... See more

The Sunway TaihuLight supercomputer is the world's most powerful and has a processing power of 93 petaflops

A group of scientists is taking to the skies to chase the shadow of the moon during the total solar eclipse on Aug. 21 from the unique vantage point of two retrofitted WB-57F jet planes.

Amir Caspi, a scientist at the Southwest Research Institute in Boulder, Colorado, and his team will soar 50,000 feet over Missouri, Illinois and Tennessee in jets outfitted with high-tech telescopes. At this altitude, the telescopes mounted on the noses of the planes will be able to capture a clear view of the outer layer of the sun's atmosphere, or the corona; they may also capture thermal images of Mercury, a planet typically obscured by the bright glare from the sun. ...
