Mars is already dirty: Humans have left more than 15,000 pounds of trash on the red planet

One scientist estimates that there are 15,694 pounds of trash on Mars.  Most of it comes from discarded hardware like this thermal blanket that protected NASA's perseverance from surviving its descent through the infernal atmosphere.

Humans have left more than 15,000 pounds of trash on Mars in the past 50 years, and not a single person has ever set foot on the red planet. Cagri Kilic, a postdoctoral researcher in robotics at West Virginia University, analyzed the mass of all the rovers and orbiters sent to Mars and subtracted the …

Search! On Monday, Jupiter will make its closest approach to Earth in 59 years for “extraordinary” views.

Stargazers are in for a great show as Jupiter makes its closest approach to Earth since 1963 on Monday evening.  Above: This photo of Jupiter, taken by the Hubble Space Telescope on June 27, 2019, shows the Great Red Spot, an Earth-sized storm that has been raging for hundreds of years.

Stargazers, look up! Jupiter will come closest to Earth in 59 years on Monday for ‘extraordinary’ views, despite being 367 million miles away Jupiter will make its closest approach to Earth since 1963 on Monday night The planet will be 367 million miles from us at its closest point The giant planet will rise in …

Global shark map REVEALED: Scientists identify areas where animals are most vulnerable

A new set of global criteria will help identify important areas for sharks, rays and chimaeras to ensure the protection they desperately need from extinction.  Pictured: Conservation reference map based on shark area

As apex predators, sharks provide many vital functions to maintain a balanced ecosystem. Sharks shape fish communities, ensure species diversity, and even help our oceans sequester more carbon by maintaining seagrass meadows. But their apex status makes them more susceptible to human threats. Many of these species are affected by fishing, especially in tropical and …

James Webb telescope captures ‘stunning’ image of Orion Nebula that formed 4.5 billion years ago

NASA's James Webb Space Telescope has captured the most detailed image of the Orion Nebula 1,344 light-years from Earth, which experts say could provide clues about the first million years of our own system solar

The Orion Nebula, which formed more than 4.5 billion years ago, is full of colorful gas, molecular material, dust and scattered starlight, and a new image captured by the James Webb Space Telescope (JWST ) from NASA is the first to look at the cosmic formation. center, allowing researchers to better understand how massive stars …

Blood of NASA astronauts shows signs of DNA mutations due to spaceflight and should be monitored

The researchers collected whole blood samples from the astronauts twice, ten days before the space flight and on the day of landing, as well as white blood cells that were collected only once, three days after landing.  Above: Official portrait of Expedition 45/46 long-duration astronaut Scott Kelly

Astronauts’ blood may show signs of DNA mutations after spaceflight, and so their cancer risk should be monitored, a new study reveals. Fourteen astronauts from NASA’s space shuttle program who flew between 1998 and 2001 on shuttle missions averaging 12 days took part in the study: 85% were men and six were on their first …

NASA’s James Webb Spots Stunning ‘Einstein Ring’ 12 Billion Light Years From Earth

The impressive Einstein ring was spotted by NASA's James Webb Space Telescope.  It is 12 billion light years from Earth

NASA’s James Webb Space Telescope (JWST) has captured a near-perfect “Einstein ring,” a bull’s-eye pattern that forms when light from one galaxy or star passes through another galaxy or massive object , 12 billion light years from Earth: a light. year is about six trillion miles. First predicted by Albert Einstein in 1915, the bright …
