Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4. Galaxies, such as the Milky Way, are the building blocks of the universe, each comprised of up to several hundred billion stars. Galaxies beyond our immediate neighborhood are rushing away, faster if they are more distant, which is a consequence of the expansion

NASA’s mission to deflect asteroid is a step towards preparing the world for a potential future asteroid strike like the one which killed the dinosaurs some 66 million years ago, the chances of which are very slim in our lifetime, Indian scientists said. In a first-of-its-kind mission, the Double Asteroid Redirection Test (DART) spacecraft successfully

NASA’s DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world’s first test of a planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth. Humanity’s first attempt to alter the motion of an asteroid or any celestial body played out in a NASA webcast from

Ten months after launch, NASA’s asteroid-deflecting DART spacecraft neared a planned impact with its target on Monday in a test of the world’s first planetary defense system, designed to prevent a doomsday collision with Earth. The cube-shaped “impactor” vehicle, roughly the size of a vending machine with two rectangular solar arrays, was on course to

If an earthquake strikes in the not too distant future and survivors are trapped under tonnes of rubble, the first responders to locate them could be swarms of cyborg cockroaches. That’s a potential application of a recent breakthrough by Japanese researchers who demonstrated the ability to mount “backpacks” of solar cells and electronics on the

A US astronaut and two Russian cosmonauts are set to blast off to the International Space Station Wednesday on a Russian-operated flight despite soaring tensions between Moscow and Washington over Russia’s invasion of Ukraine. NASA’s Frank Rubio and Russia’s Sergey Prokopyev and Dmitry Petelin are scheduled to take off from the Russia-leased Baikonur cosmodrome in

Mars, by virtue of its tenuous atmosphere and proximity to our solar system’s asteroid belt, is far more vulnerable than Earth to being struck by space rocks – one of the many differences between the two planetary neighbours. Scientists are now gaining a fuller understanding of this Martian trait, with help from NASA’s robotic InSight

NASA’s James Webb Space Telescope, known for capturing some incredible images of the universe, has presented us with new pictures of our neighbouring planet, Mars. The telescope captured its first images and spectra of Mars on September 5. The James Webb Space Telescope, an international collaboration between NASA, ESA (European Space Agency) and CSA (Canadian

American space agency NASA has updated its Eyes on the Solar System website, which allows space enthusiasts to explore the “universe beyond and the spacecraft exploring them”. Visitors can explore the planets, their moons, asteroids, comets and the spacecraft from 1950 to 2050. The website also allows them to simulate the landing of NASA’s spacecraft,

India’s first human space-flight mission, Gaganyaan, is expected to launch in 2024, Union Minister Jitendra Singh said recently. The government had planned the space flight for 2021, but the schedule got delayed due to the COVID-19 pandemic. The first test-flight will be followed by a female-looking spacefaring humanoid robot. The Indian Air Force (IAF) has

NASA’s James Webb Space Telescope has captured in-depth details of a stellar nursery nicknamed the Tarantula Nebula. Webb’s recent image of the 30 Doradus, or Taratula Nebula, displays several never-before-seen young, with galaxies in background. The picture also reveals the composition of the nebula’s gas and dust. Located around 161,000 light-years away from us, Tarantula has
