A NASA team streamed 4K video footage from an aircraft to ISS and back for first time using laser technology. Laser communications use infrared light, capable of transmitting more data at faster speed than radio frequency systems, which NASA used in past to send information. Scientists hope this technology could provide live coverage of astronauts on Moon during Artemis missions.

An 880-foot stadium-sized asteroid is approaching towards Earth at a speed of 22,333 kmph today, National Aeronautics and Space Administration (NASA) said. The asteroid is expected to fly by Earth tonight (IST), the space agency added. The asteroid is named 2011 AM24 and it is part of the Apollo asteroid group.

Rock varnish in Ladakh, formed through biotic processes, mirrors Martian varnish observed by the Perseverance rover. Researchers found organic signatures and magnetic minerals in Ladakh's rock varnish, suggesting it can archive ancient environmental records. This discovery could help identify potential biosignatures on Mars and other planetary bodies, crucial for finding habitable environments.

Sunita Williams has been in space for over 50 days on Boeing Starliner's flight, which was supposed to be a 10-day mission. NASA said Williams investigated using fluid physics, such as surface tension, to overcome lack of gravity when watering and nourishing plants being grown in space. This is a vital step towards understanding how plants respond to microgravity conditions.

In a surprising yet exciting turn of events, Esteban Ocon has signed with Haas for the 2025 season, marking a significant shift in his Formula 1 career. Ocon, a seasoned driver with 146 race starts and a race victory under his belt, joins Haas alongside rookie Ollie Bearman. This decision comes well before the summer break.

On July 24, 1969, Apollo 11 astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins had to fill out customs declaration forms upon returning to Earth at Honolulu Airport. The form humorously listed their route as Cape Kennedy to the Moon and back, with their cargo described as "moon rocks and moon dust samples". This formality was more symbolic than procedural.

A team of researchers has raised concerns over the rapid development and lack of regulation of 'Living robots' or bio-hybrid robots made with living tissue grown in labs. "Bio-hybrid robots create unique ethical dilemmas...[as well as] potential dangers," the researchers said. They raised questions over their ability to sense the surroundings and the subsequent moral values.

Komodo dragons, the world's largest species of lizard, have iron-tipped teeth that help them to rip their prey apart, according to new study led by researchers from King's College London. Komodo dragons prey on a range of animals from rodents to water buffalo and kill using their sharp teeth and venomous bite. Humans have also been killed by the lizards.

A super Jupiter has been discovered by the Webb Space Telescope orbiting the star Epsilon Indi A. This massive planet, six times Jupiter's mass, has hydrogen-rich atmosphere and a diameter similar to Jupiter's. It takes over a century, possibly up to 250 years, to complete its orbit. It's situated 15 times further from its star than Earth is from Sun.

Asteroid 2011 MW1, about 380 feet in diameter, will closely approach Earth today, that is, on July 25. Travelling at 28,946 kmph, it's classified as a Near Earth Asteroid (NEA). Despite its size and speed, NASA assures there is no risk of impact, with the asteroid passing within 2.4 million miles of Earth, a distance considered safe.
