Scientists say humans would have had a “leaner” physique with long legs and narrow hips around 1.5 million years ago.
The new research by two physicists adds to astronomical knowledge—and overturns previous Biblical interpretations.
It now seems that human bodies out in the unmoored weightlessness of space start developing anatomical anomalies – including the movement of key neurological features in the brain and spine, reports a team of scientists from the Medical University of South Carolina in the New England Journal of Medicine.
Indigenous peoples around the world have understood the stars, tides and local ecosystems for hundreds of years but experts say their insights have often been overlooked. Now some female scientists are striving to highlight their achievements and collect the scientific heritage of their communities before it disappears.
This finding means that the star, which is also home to the nearest Earth-like planet discovered just last year, hosts what could be a more elaborate planetary system than we previously thought.
Tonight (Nov. 5), just one day after reaching its full phase for the month, the moon will temporarily hide the orange star Aldebaran, the brightest star in the constellation Taurus, in what astronomers call an occultation.
The list of passengers for the first interstellar space mission has been released and, sorry Elon, you’re not on it and neither are any other Trekkie-wannabes – with or without their own rockets.
An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.
Two teams of physicists used figures from the variety of gravitational waves to narrow estimates on just how fast we think gravity moves, and while their results aren’t shocking, they are strangely comforting.
The most ancient spiral galaxy discovered to date is revealing its secrets. Researchers combined gravitational lensing with the Near-infrared Integral Field Spectrograph in Hawai‘i to verify the vintage and spiral nature of this galaxy. The galaxy, known as A1689B11, existed 11 billion years in the past, just 2.6 billion years after the Big Bang, when the Universe was only one fifth of its present age. It is thus the most ancient spiral galaxy discovered so far.
There is a rich heritage of interpreting dusk and dawn sky colours, with different cultural groups and peoples having different traditions and sayings. For example, “shepherd’s delight” is typically replaced with “sailor’s delight” in the US version of the rhyme. But is there any truth behind such forecasting? It seems there is indeed some truth to the old saying about red skies at night.
A diagnostic tool, similar in theory to those used by the medical profession to non-invasively image internal organs, bones, soft tissue, and blood vessels, could be equally effective at “triaging” extraterrestrial rocks and other samples non-destructively before they are shipped to Earth for further analysis.
Scientists from MIT and other institutions, working closely with amateur astronomers, have spotted the dusty tails of six exocomets ~ comets outside our solar system ~ orbiting a faint star 800 lightyears from Earth. These cosmic balls of ice and dust, which were about the size of Halley’s Comet and traveled about 100,000 miles per hour before they ultimately vaporized, are some of the smallest objects yet found outside our own solar system.
Researchers from the University of Cambridge have pinpointed the date of what could be the oldest solar eclipse yet recorded. The event, which occurred on 30 October 1207 BC, is mentioned in the Bible, and could have consequences for the chronology of the Ancient World.
