A stadium-sized asteroid will pass relatively “close” to Earth this weekend, but experts say not to worry.

NASA’s Jet Propulsion Laboratory (JPL) is monitoring Asteroid 2002 NN4—believed to be more than 1,000 feet in diameter—ahead of its anticipated flyby Saturday.

Although the asteroid is on NASA’s “close approach” list, a representative for JPL told USA Today that the space rock will pass at a safe distance of more than 3 million miles—about 13 times farther than the distance from Earth to the moon.

Scientists have unveiled the world's most sensitive strain sensor, capable of detecting the weight of a single feather.

The sensor is significantly more stretchable, capable of enduring 80 times greater strain than current commercial sensors, and is able to register resistance changes with 100 times the precision of current sensors, researchers said.

The Dance of Venus and Earth
Every time Venus passes the Earth, it shows the same face. This remarkable fact has been known for only about 50 years, ever since radio telescopes have been able to peer beneath Venus' thick clouds and track its slowly rotating surface. This inferior conjunction -- when Venus and Earth are the closest -- occurs today. The featured animation shows the positions of the Sun, Venus and Earth between 2010-2023 based on NASA-downloaded data, while a mock yellow 'arm' has been fixed to the ground on Venus to indicate rotation. The reason for this unusual 1.6-year resonance is the gravitational influence that Earth has on Venus, which surprisingly dominates the Sun's tidal effect. If Venus could be seen through the Sun's glare today, it would show just a very slight sliver of a crescent. Although previously visible in the evening sky, starting tomorrow, Venus will appear in the morning sky -- on the other side of the Sun as viewed from Earth.

There are four planets in the Solar System that have rings — Jupiter, Saturn, Uranus, and Neptune. A new study, however, suggests that Mars may have also once been a ringed planet.

The remains of one of the last carnivorous dinosaur to roam the Earth have been found in Argentina. Experts uncovered what was once a 33-foot long megaraptor that lived 70 million years ago.

The dreaded dinosaur Allosaurus was the scourge of the Jurassic Period landscape some 150 million years ago, an apex predator just as Tyrannosaurus rex was 80 million years later during the Cretaceous Period.

SpaceX is preparing for its first crewed launch: Its Crew Dragon spaceship is scheduled to carry two NASA astronauts into orbit on Wednesday, starting at 4:33 p.m. ET.

NASA and SpaceX are broadcasting live audio from the mission, called Demo-2, on NASA TV's YouTube channel, which is embedded below. You'll be able to hear what the veteran astronauts Bob Behnken and Doug Hurley say aboard the SpaceX spacecraft as the rocket launches from Cape Canaveral, Florida.

Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. The new type of explosion shares some characteristics with supernova explosions of massive stars and with the explosions that generate gamma-ray bursts (GRBs), but still has distinctive differences from each.
