The solar system is about to get busy! In the next few weeks, a slew of spacecraft will embark on a one-way 314-million-mile (505-million-kilometer) journey to Mars, to seek evidence of past life and to further investigate its unusual atmosphere. The back-to-back missions are timed to take advantage of the short window of opportunity — caused by celestial mechanics — that will allow them to reach the Red Planet in the most efficient and cost-effective manner.
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.
The unwarranted death of George Floyd, an unarmed African American man, by a Minneapolis, MN, police officer on May 25, 2020, has reignited the debate about race-based police abuse. Protestors argue that the current law enforcement system encourages systemic racism and are calling for nationwide police reform.

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.
Researchers have long believed that all four-limbed animals or tetrapods, a group that includes amphibians, reptiles, and mammals, evolved from an ancient group of fish known as Elpistostege watsoni, which lived between 416 million and 358 million years ago, during the Devonian Period.
