A Violent Splash of Magma That May Have Made the Moon

The moon is far more than a largely dead orb. Our planet’s pale satellite is the creator of tides, the catcher of meteors and the only other world in the starry ocean where humanity has set foot. But scientists are still not entirely clear how it was made. Solving this mystery would not only reveal the moon’s origins, it would also help explain our own planet’s evolution.

A study suggests that the moon was forged from the fires of an ocean of magma sloshing over baby Earth’s surface. If correct, this model may solve a longstanding paradox.

Blue supergiant stars open doors to concert in space

Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our knowledge of these stars was limited. Using recent NASA space telescope data, an international team led by KU Leuven studied the sounds originating inside these stars and discovered that almost all blue supergiants shimmer in brightness because of waves on their surface according to Science Daily.

Since the dawn of humanity, the stars in the night sky have captured our imagination. We even sing nursery rhymes to children pondering the nature of stars: "Twinkle, twinkle little star, how I wonder what you are". Telescopes are able to probe far into the universe, but astronomers have struggled to 'see' inside the stars. New space telescopes allow astronomers to 'see' the waves that originate in the deep interior of the stars. This makes it possible to study these stars using asteroseismology, a similar technique to how seismologists use earthquakes to study the Earth's interior.

Climate change: How frogs could vanish from ponds

Climate change is having an impact on frogs found in British ponds, research suggests.

A deadly frog disease is spreading due to warmer temperatures and in the next 50 years could cause entire populations to vanish, according to a study.

The virus could spell disaster for the common frog, which is a familiar sight in garden ponds and the countryside, according to BBC.

Amphibians have been particularly hard hit by changes in the natural world.

Astronomers discover 2,000-year-old remnant of a nova

For the first time, a European research team involving the University of Göttingen has discovered the remains of a nova in a galactic globular cluster. A nova is an explosion of hydrogen on the surface of a star which makes it much brighter. The remains have formed a glowing nebula. The remnant is located near the centre of the globular cluster Messier 22 and has recently been observed using modern instruments, according to Science Daily.

"The position and brightness of the remains match an entry from 48 BC in an ancient collection of observations by Chinese astronomers," says first author Fabian Göttgens of the Institute for Astrophysics at the University of Göttingen.

'Exhilarating' implant turns thoughts to speech

Scientists have developed a brain implant that can read people's minds and turn their thoughts to speech.

The team at the University of California, San Francisco says the technology is "exhilarating".

They add that their findings, published in the journal Nature, could help people when disease robs them of their ability to talk.

Experts said the findings were compelling and offered hope of restoring speech.

The mind-reading technology works in two stages.

First an electrode is implanted in the brain to pick up the electrical signals that manoeuvre the lips, tongue, voice box and jaw.
