A massive dust cloud that had been journeying 5,000 miles from the Sahara Desert across the Atlantic Ocean since June 15, 2020, finally hit the United States mainland on June 26, 2020. Nicknamed "Godzilla," the 3,500 mile-long plume broke into two chunks, thanks to the split in the mid-levels of the atmosphere....

Since May 26, 2020, cities across the US have been gripped by protests seeking justice for George Floyd, an unarmed African American man who died in police custody on May 25, 2020. The incident has led to one of the biggest displays of unrest seen in America in 50 years and reignited the debate about law enforcement and race relations globally. From May 30 to June 1, 2020, thousands of demonstrators in cities across the world — from London to Berlin to Auckland to Brazil — marched in solidarity with their US counterparts to demand justice for Floyd and to protest against the mistreatment of minority groups in their respective countries....

Due to COVID-19, the Class of 2020 is missing out on a traditional graduation. However, those who accepted SpaceX's invitation to upload selfies to the company's website will commemorate their milestone year with a journey most people only dream about....

Given that each light-year — defined as the distance light travels in one Earth year — is about 6 trillion miles (9 trillion km), a black hole that lies 1,000 light-years away may not seem very close. However, to astronomers who are accustomed to cosmic distance scales, the recently-discovered HR 6819's black hole, which lies in the constellation Telescopium, is an extremely close neighbor....

"Glow in the dark" dolphins may seem like something straight out of a science fiction movie. However, that is precisely what Newport Coastal Adventures' Captain Ryan Lawler and professional videographer Patrick Coyne witnessed on April 22, 2020, when they set out to explore the spectacular neon blue tides that have been lighting up the waters off Southern California's coast since mid-April....

While the novel coronavirus is dangerous for everyone, it is particularly so for the first responders who are being exposed to the illness daily. In the US alone, almost 5,500 nurses, doctors, and other healthcare professionals have been infected with COVID-19. Of these, dozens have succumbed to the disease. Now, hospital workers worldwide may get some reprieve thanks to Spot, a semi-autonomous four-legged robot developed by Waltham, Massachusetts-based robotics company, Boston Dynamics....

Though considered a waste of time by some, sleep is essential for the health and wellbeing of humans. Over the years, researchers have found sleeping allows the body to repair and restore cells, get rid of irrelevant memories, and even help kids grow taller and obtain better grades. Now, it appears that snoozing for an average of 8 hours daily enables the brain to cleanse itself and get rid of harmful toxins....

NASA's X-plane program, established in 1946 to test and evaluate new technologies and aerodynamic concepts, began with the launch of the X-1 — the first plane to break the sound barrier. Since then, the endeavor has led to numerous industry breakthroughs, including the first supersonic and hypersonic flights, and the first crewed suborbital flight....

After an extensive 14-year, $6.6 million restoration, Egypt's oldest pyramid was reopened to the public on March 5, 2020. Located in the Saqqara necropolis, northwest of the city of Memphis, the Pyramid of Djoser was built 4,700 years ago as a tomb for Pharaoh Djoser, the first king of the 3rd dynasty (2650–2575 BCE). The massive pyramidal funerary complex was neglected for centuries and almost on the verge of collapse before Egyptian officials finally decided to take action in 2006 and bring it back to its former glory....

With over three-quarters of the country under mandatory shutdown orders, and more joining daily, the COVID-19 pandemic has forced hundreds of businesses to shutter and led to widespread layoffs. To mitigate the coronavirus outbreak's economic impact, US lawmakers have passed a $2.2 trillion emergency relief bill, the largest economic rescue package in the nation's history....

Over the years, researchers have unearthed fossils of many of the estimated 2,468 dinosaur species that roamed Earth during the Mesozoic era, which spanned from between 252 million years ago to about 66 million years ago. However, few can compare to the discovery of Oculudentavis khaungraae, the smallest dinosaur ever known to live on the planet....

With schools and businesses closed and many cities and towns under mandatory shelter-in-place orders, the novel coronavirus, or COVID-19, has drastically changed lives globally within a matter of weeks. To bring joy, optimism, and strength during this difficult period, people and organizations worldwide are performing random acts of kindness for total strangers. Here are a few heartwarming deeds that will bring a smile to your face during these unprecedented times....

On March 11, 2020, the World Health Organization (WHO) announced that the COVID-19 coronavirus global emergency is now a pandemic. The UN health agency urged countries worldwide to "double-down" on their efforts to curtail the spread of the infectious disease, which has swept into at least 114 countries and killed over 4,000 people in less than three months....

Though many single-celled lifeforms have evolved to survive without oxygen, multicellular organisms have always been believed to need it to live. Now, scientists in Tel Aviv, Israel, have found that Henneguya salminicola, a parasite, which spends its life attached to the muscle tissue of fish, has adapted to living without oxygen....

Celebrated annually on March 14, Pi ("π”) Day is a universal favorite with students and teachers. Though the American holiday, which honors the numerical constant representing the ratio of a circle's circumference to its diameter, typically begins with a classroom discussion of the symbol, it usually ends with a slice or two of delicious pie. The event is commemorated every March 14 because the irrational number, which continues infinitely without repetition or pattern, is widely recognized as 3.14....

Though India is home to numerous fun festivals, few are as revered or as widely celebrated as Holi, the festival of colors. Commemorated annually on the last full moon day of the Hindu calendar month Phalguna, this year, the joyous holiday will take place on March 10, 2020....

Since the beginning of 2020, the East African country of Kenya has been battling the nation's worst desert locust outbreak in over 70 years. The destructive swarms, some as big as three times the size of New York City — an estimated 192 billion insects — are eating their way through thousands of acres of crops and animal pastures, decimating livelihoods in the process. Even worse, the locusts, which arrived from neighboring Somalia and Ethiopia, are now spreading to other countries, including Uganda, South Sudan, Tanzania, and Congo....

While jewelry crafted from gold can be gorgeous, even ardent fans will admit that wearing the heavy metal over long periods of time can get a little cumbersome and annoying. Now, researchers from Swiss university ETH Zurich have created a new form of lightweight gold that weighs five to ten times less than traditional 18-carat gold — which typically comprises 75 percent gold and 25 percent copper — but retains the same purity....

In what can only be described as an extraordinary engineering feat, NASA scientists have remotely fixed a software glitch on the Voyager 2 probe, which lies 11.5 billion miles away at the edge of a transitional region of space.
