Special star is a Rosetta Stone for understanding the sun's variability and climate effect

The spots on the surface on the Sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete. One example is the so-called Maunder Minimum, a period in the 17th century, where spots almost disappeared from the surface of the Sun for a period of over 50 years, according to Science Daily.

How did Mars lose its oceans? Scientist may have cracked the mystery

Mars might not be as dry as previously thought. New research from the University of Oxford suggests the water which once flowed on the Red Planet’s surfaces is actually locked in its rocks.

It has been accepted for some time that streams of water used to flow along the surface of Earth’s barren neighbor. But the reason for the water’s disappearance has never been fully understood, according to RT.

Scientists describe how solar system could have formed in bubble around giant star

Despite the many impressive discoveries humans have made about the universe, scientists are still unsure about the birth story of our solar system, according to Science Daily.

Scientists have laid out a comprehensive theory for how our solar system could have formed in the wind-blown bubbles around a giant, long-dead star, the study addresses a nagging cosmic mystery about the abundance of two elements in our solar system compared to the rest of the galaxy.

Star in the constellation Pisces is 'eating' planets

Like the ancient Greek god Cronus who devoured his children, a star 550 light years from Earth has been discovered to be slowly consuming its "offspring" -- crushing one or more planets in its orbit into vast clouds of gas and dust according to Science daily.

The discovery may shed light on a brief but volatile period in the history of many solar systems, including our own.

"We know it's not uncommon for planets to migrate inward in young solar systems since we've found so many solar systems with 'hot Jupiters' -- gaseous planets similar in size to Jupiter but orbiting very close to their stars," said Pilachowski. "This is a very interesting phase in the evolution of planetary systems, and we're lucky to catch a solar system in the middle of the process since it happens so quickly compared to the lifetimes of stars."

Bruce McCandless, who made first untethered space flight, dies at 80

Bruce McCandless, who was captured in a stunning photograph in 1984 as he made the first untethered flight in space, has died aged 80, Nasa said.

With a jetpack, McCandless travelled 100m (328ft) from the Space Shuttle , according to BBC.

"That may have been one small step for Neil, but it's a heck of a big leap for me," he joked, adapting astronaut Neil Armstrong's famous moon-landing line.

Armstrong's words were in fact relayed to McCandless, who was in mission control for the moon landing in 1969.
