NASA’s OSIRIS-REx mission prepares for touchdown on an asteroid

This week, the OSIRIS-REx spacecraft conducted a final rehearsed of all of the maneuvers it will need to touchdown on the asteroid Bennu and collect a sample from it in the fall. The collection will occur on October 20, making it NASA’s first spacecraft to collect a sample from an asteroid and return it to…

Hubble spies the culprit behind Betelgeuse star’s dimming. And it may be happening again

The Hubble Space Telescope may have solved the mystery of the curiously dimming star Betelgeuse, according to new research. And to add even more intrigue to the story, the star appears to be dimming again, which is unexpectedly early based on what astronomers know about the star. The study published Thursday in The Astrophysical Journal.…

The reason we’re shooting laser beams between Earth and the moon

For the first time ever, scientists received a signal after sending laser beams from Earth to a reflector on NASA’s Lunar Reconnaissance Orbiter around the moon. The successful signal was received after multiple attempts over the last decade, and the results of the study could complement future laser experiments used to study space. A laser…

Russian power lifter fractures both knees while attempting to squat nearly 900 pounds

A Russian power lifter broke both his knees while trying to lift nearly 900 pounds. Alexander Sedykh was seriously injured while competing in the 2020 World Raw Powerlifting Federation (WPRF) Championships held in Dolgoprudny, which is in the Moscow region of Russia, the Russian state-run news agency RIA Novosti reported. In a video posted by…

Climate change spelled doom for woolly rhinos 14,000 years ago, study says

Woolly rhinos went extinct at the end of the last ice age in Siberia about 14,000 years ago, and now ancient DNA is helping to shed light on what really happened to them and other large mammals. Previously, it was believed that humans hunted these giant animals as they spread across the globe. But new…

This 429 million-year-old trilobite eye is similar to those of modern insects

Eyes don’t typically appear in the fossil record, but researchers were able to study the well-preserved and fossilized internal structure of a 429 million-year-old trilobite eye. Surprisingly, they found that the structure of the eye was nearly identical to the compound eyes of modern bees, dragonflies and crustaceans, according to the new study. The study…

Last decade was Earth’s hottest on record, exposing grim reality of climate change

A new report released Wednesday details how 2019 was another year of extremes for Earth’s climate, adding to a litany of evidence exposing the grim reality of our warming world. Last year saw devastating wildfires burn through Australia; large regions including Europe, Japan, Pakistan, and India experienced deadly heat waves; almost 100 tropical cyclones created…

Birds and reptiles cry similar tears to humans, says new research

Birds and reptiles may not resemble humans in many ways, but they cry similar tears. The composition of human tears is well known, but until now, there was very little research into the composition and structures of tears in reptiles, birds and other mammals. That lack of research could be considered a crying shame since…

Astronomers find galaxy similar to Milky Way more than 12 billion light-years away

Our Milky Way galaxy has a bit of a look-alike in an unlikely place: the early universe. Astronomers used ALMA, or the Atacama Large Millimeter/submillimeter Array of telescopes, based in Chile, to find the galaxy located more than 12 billion light-years away from our own. That means the light from this galaxy has traveled for…

Regular bricks can be transformed into energy storage devices

Whether humans were erecting Neolithic dwellings, ranch-style homes or modern McMansions, bricks have been a favorite of builders for thousands of years. Now, chemists have discovered new potential in these ubiquitous building blocks: Through a series of reactions, scientists have shown that conventional bricks can be transformed into energy storage devices powerful enough to turn…

Gray reef sharks form long-lasting social groups likely for hunting, study shows

We can’t quite say sharks can be friends, but new evidence is showing us that sharks form social bonds with others and can work together — to a degree. Gray reef sharks regularly meet up together in the same groups, according to a new study published on Tuesday in the Proceedings of the Royal Society.…
