An international team of astrophysicists has reported the discovery of a unique cosmological gamma-ray burst (GRB) that defies current theories of how the violent cosmic explosions form. This exceptional burst has resulted in a new proposed model, or source, for certain types of gamma-ray bursts.

To find evidence of prehistoric microbial life and to better understand the processes that formed the surface of Mars, scientists wish to analyze Martian samples with high-tech lab equipment on Earth. The majority of the samples will be made up of rock. Still, scientists are also interested in studying regolith, or broken rock and dust, not only for what it can reveal about Mars’ geological processes and environment but also help astronauts prepare for some of the difficulties they will encounter. Regolith is fascinating to scientists and engineers because it can impact everything from solar panels to spacesuits.

In the summer of 2020, NASA launched Percy (full name, Perseverance), a car-sized rover, as part of the Mars 2020 mission. For seven long months, Percy traveled through the vacuum of space, drifting among the stars toward the Red Planet with a small robotic helicopter fondly dubbed Ginny (Ingenuity) in tow.

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat.

Astronomers have spotted a bright gamma-ray burst that upends previous theories of how these energetic cosmic eruptions occur.

Last December, astronomers caught sight of an extremely bright, extremely close gamma ray burst that lasted for a little under a minute — close as far as gamma ray bursts, anyways: about a billion light-years away. Ordinarily, it would be interesting, but nothing groundbreaking, something to be filed away with the tens of thousands of other long gamma ray bursts that have been observed over the past half-century. But then, something didn’t happen: the supernova required to create such a lengthy explosion was nowhere to be found.

NASA’s Perseverance rover snagged two new samples from the Martian surface on Dec. 2 and 6. But unlike the 15 rock cores collected to date, these newest samples came from a pile of wind-blown sand and dust similar to but smaller than a dune. Now contained in special metal collection tubes, one of these two samples will be considered for deposit on the Martian surface sometime this month as part of the Mars Sample Return campaign.

More than a year and a half after its first flight on Mars, the Ingenuity helicopter has set a new record.

Social media is flooded with posts that claim to prove the Earth is flat. A recent example is a post that claims a photo of Chicago taken from Indiana demonstrates the Earth's flatness.

Mankind's crucial fossil fuels—coal, natural gas and crude oil—all unfortunately contain large amounts of carbon. But why is that and where does it come from?

Certain metals are essential to producing renewable energy products, and tellurium (Te) is one that is becoming more widely used in the manufacturing of photovoltaic cells for solar panels.

Five major El Niño events per century could lead to fewer fishes that thrive in cold water and more terrestrial birds in eastern coastal ecosystems.
