Objects such as satellites and rocket debris constantly fall out of orbit and burn up upon re-entry into Earth's atmosphere before they can hit the surface. Still, larger pieces like the Long March 5B rocket can survive re-entry and pose a threat to inhabited areas.

Debris From China's Recent Rocket Launch Plunged Into the Indian Ocean

The rocket's uncontrolled orbit was tracked for days and, upon re-entry, received criticism from NASA

One of the cats from the experiment sits in a Kanisza square, which is four Pac-Man-like circles positioned to create four corners of a square.

Nepal opened up Mount Everest and its other seven peaks this year in hopes of regaining tourists after their mountaineering economy took a devastating hit.

As Cases Surge in Nepal, Covid-19 Reaches Mount Everest

Base camp officials have seen rising numbers of climbers with symptoms and positive coronavirus tests

Using the detected radio wave, Collinson and his team calculated the density of Venus' ionosphere and compared it to measurements taken back in 1992 using the Pioneer Venus Orbiter.

NASA's Parker Solar Probe Measures Radio Signal in Venus' Upper Atmosphere

The measurements help researchers understand how the planet's ionosphere began leaking

After the researchers combed through more than 27,000 photos of birds from nine accounts across Instagram, they found that it is more than just beauty that attracts ‘likes’. Peculiar or distinctive characteristics that make the bird more unique is what people respond to the most and brings in the most 'likes';

The Eccentric Frogmouth Is the Most Camera-Ready Bird on Instagram

The frogmouth has muted plumage, but its grumpy expression and wide eyes make it enchanting on social media

As  the NASA aircraft DC-8 flew into the storm and collected data after each lightning flash, the researchers found that the concentrations of hydroxyl and hydroperoxyl produced by visible lightning and other regions that were electrically charged soared up to thousands of parts per trillion.

Lightning May Wash Pollution Out of the Air With a Chemical Dubbed 'Detergent of the Atmosphere'

The oxidizing chemicals hydroxyl and hydroperoxyl may clean the skies of harmful pollutants by reacting with them

Designed to operate for more than a decade, the Chinese Space Station will have 14 refrigerator-sized experiment racks and 50 external docking points designed for experiments outside the station to test how materials react in space.

China Launches First Module of New Space Station Into Orbit

The module is the country's largest spacecraft ever built and marks the first step in building their new space station by 2022

Traditionally, when taxonomists examine a potentially new species of octopus, they dissect them, an approach that is highly invasive and nearly destroys the specimen.

New Species of Dumbo Octopus Identified Using 3-D Imaging Techniques

Techniques such as MRI and CT scans may allow researchers to identify and study rare sea specimens without the need for dissection

From soil samples, researchers found urine droplets and fecal material that belonged to Upper Paleolithic bears that used the Chiquihuite Cave as their shelter and toilet 16,000 years ago.

Using Only Trace Amounts of Poop in Soil Samples, Researchers Sequenced Entire Genomes of Two Ancient Bear Species

Genetic research involving prehistoric animals usually requires fossilized bone or tooth fragments

The disastrous Chernobyl Nuclear Power Plant accident occurred on April 26, 1986, after a flawed reactor design caused two explosions that broke Chernobyl's No. 4 Reactor.
