On the heels of the spectacular May 26, 2021, total lunar eclipse comes another celestial spectacle. On June 10, 2021, some lucky stargazers will witness this year's first of two solar eclipses. Since it is an annular, not a total, eclipse, the Sun's edges will be visible around the Moon, transforming the star into a stunning "ring of fire."
Given that white was one of the first colors used in art in the 15th century, one would think that there is little room left to improve its "whiteness." It turns out that is far from the case. A team of researchers led by Xiulin Ruan, a professor of mechanical engineering at Indiana's Purdue University, recently revealed an "ultra-white" paint that they believe could even help combat climate change.
A collection of 1,000 prehistoric structures dubbed mustatils — the plural form of the Arabic term for rectangles — scattered across 124,274 miles (200,000 kilometers) in northwest Saudi Arabia may be the world's oldest monuments. A team of archeologists from the University of Western Australia (UWA) reached this conclusion after radiocarbon dating of charcoal found inside the courtyards indicated they were constructed in 5,000 BC — or about 2,000 years before the Egyptian pyramids or monuments like Stonehenge in southern England.
Geologists have long maintained that our Earth comprises four layers — the crust, the mantle, the outer core, and, the deepest layer, the inner core. However, a team of scientists led by Jo Stephenson, a doctoral student in seismology at Australian National University in Canberra, now asserts that our planet may be harboring a mysterious, fifth layer — an "inner-inner" core as well.
Researchers worldwide are celebrating the discovery of the fossil of an adult oviraptorosaur brooding over a nest of eggs containing unhatched babies. The unprecedented discovery confirms scientists' suspicions that the two-legged bird-like dinosaurs were doting parents, which not only incubated their eggs, but also guarded them —at times putting their own lives at risk.
On April 22, 2021, for the second consecutive year, the US House of Representatives voted 216-208 to make Washington, DC, the nation's 51st state. Though the symbolically titled H.R. 51 bill is identical to the one passed on June 26, 2020, the legislation was never put to the vote in the then Republican-controlled Senate. However, this time around, the bill — which has the support of both President Joe Biden and Democratic Majority Leader Charles E. Schumer — will get a hearing in the upper house of Congress.
NASA made history on April 19, 2021, by conducting the first controlled flight of an aircraft on another planet. In what is being described as a "Wright brothers moment," the tissue-box-sized Ingenuity gradually ascended to an altitude of 9.8 feet (3 meters) above the surface of Mars and hovered for 30 seconds before gracefully descending to land on its four legs.
When 36-year-old Andy Duran decided to return to his favorite high school hobby — skateboarding — in January 2021, the only obstacle he expected to encounter was his own ability to get back into the sport after the long hiatus. However, the 340-pound skateboarder from Oakland, California, soon realized that was the least of his problems.
