With Winter coming, air pollution in India is going to once again hit crisis levels soon. At the individual level we can wear masks and use air purifiers in our homes, but more broadly, cities and municipalities have also been installing outdoor air purifiers over several years now — but do these actually work? Have

NASA has announced that it was now targeting to launch the Artemis 1, an uncrewed mission that will return the American space agency to the Moon after decades, in February 2022. The rescheduling of the launch has delayed the mission by at least three months as the ambitious programme was initially set to take off

NASA said Friday it is now targeting February 2022 for the uncrewed lunar mission Artemis 1, the first step in America’s plan to return humans to the Moon later this decade. The space agency had initially wanted to launch the test flight by the end of this year, with astronauts on the ground by 2024

In a first, surgeons have successfully attached a pig’s kidney to a human and monitored the pinkish organ function normally for more than 50 hours. They hope this breakthrough could address donor organ shortages for life-saving transplants one day. While complex medical procedures similar to this have been done before on primates, it’s the first time

NASA has shared a dramatic image of two peculiar galaxies locked in a cosmic dance. The event was taking place at a distance of about 220 million light-years from Earth in the constellation Pegasus and was captured by the space agency’s powerful Hubble Space Telescope. The image shows the diminutive galaxy almost attached to its

When mobile phones first came into existence they were big and unattractive. Several researchers then worked on making them compact and desirable. People gradually warmed up to the technology and embraced it as it allowed them to communicate on the move. There have been several advancements since, catering to various demands of the users. A

Governments all over the world are looking at energy security as a priority to power their industries, businesses, homes, and offices. But there are finite sources of energy and the technology to harness renewable energy is still decades away from a wider adoption. US-based company Radiant is trying to address this challenge by developing a

A woman had a potentially fatal experience in Canada recently. As she slept through the night a meteorite, a small meteorite pierced through her roof and came crashing on her pillow. It barely missed her head, but created a hole in the roof. The incident turned the light back on the question: What if a

An augmented reality (AR) professional 3D-printed a full-scale Velociraptor for his daughter and went on to bring it to life (virtually). A video shared by Florent Germain on Twitter shows the results of this fun experiment. Germain tweeted on October 20, “Last month, I 3D printed a full-scale Velociraptor for my daughter. Then, I went

Vaping e-cigarettes may not be useful in helping people quit smoking, a recent research suggests. The United States Centers for Disease Control and Prevention had earlier suggested that smokers could switch from puffing cigarettes to vaping e-cigarettes if they were unable to quit smoking. This came with one condition: smokers would have to completely switch

Astronomers have observed an accreting white dwarf abruptly lose and gain its brightness for the first time. White dwarfs are stars that have run out of their basic fuel: hydrogen. Usually, researchers have observed white dwarfs losing their brightness over days or months. Astronomers were studying the white dwarf binary system, TW Pictoris, and the

NASA never stops surprising us with stunning images from outer space. In a new Instagram post, the space agency has released a new photo of Milky Way on October 19.

While NASA is sending a spacecraft to Jupiter’s asteroids in an unprecedented mission to unravel the mystery of solar system’s origin, a physicist has said that a meteorite, that crash-landed in a home in Canada this month, can offer similar results. Peter G. Brown, a professor of physics and astronomy at the University of Western

Space has always intrigued humans. While many exploration missions have hitherto focussed on our neighbours like the Moon and Mars, US space agency NASA is taking the game a notch higher with its latest launch. NASA is daring to send one of its spacecraft to a place in the dark alleys of the outer solar

Virgin Galactic said on Thursday it is delaying its commercial space travel service to the fourth quarter of 2022 and will not conduct another planned test flight this year. Virgin Galactic said “commercial service is now expected to commence in Q4 2022.” Shares in the company fell 13 percent in afterhours trading. The US Federal

Maintenance of the International Space Station (ISS) can become hectic for astronauts. So, NASA has devised a way to help astronauts with their chores. Astrobee, a free-flying robotic system assistant, is NASA’s new addition onboard the ISS. The purpose of this robot is to undertake routine tasks so that astronauts have ample time to spare

Mars is quite similar to Earth, as per a NASA scientist. In a video interview, astrobiologoist Dr. Becky McCauley Rench said that the Red Planet wasn’t as dry always, as we see it today. As per NASA’s own website, “Mars, like Earth, has seasons, polar ice caps, volcanoes, canyons, and weather.” Signs of ancient floods

A team of researchers at the California Institute of Technology (Caltech) have come up with a bipedal robot that performs the twin function of walking and flying. The team claims that their latest creation is not just agile but also capable of complex movements. Named Leonardo, the part-walking robot, part-flying drone is built in such

Having made a career out of playing an explorer of the cosmos, William Shatner – Captain James Kirk of Star Trek fame – did it for real on Wednesday, becoming at age 90 the oldest person in space aboard a rocketship flown by billionaire Jeff Bezos’s company Blue Origin, an experience the actor called profound. Shatner

A moderately strong solar storm hit Earth recently and created a spectacular light show that was visible from New York. This event took place as Earth entered a period of heightened solar activity. On October 11, a massive solar flare was spotted on the Earth-facing side of the Sun and it reached the planet on

Jeff Bezos-founded Blue Origin is set to take William Shatner of Star Trek fame to space and back safely on October 13. Though the launch was pushed back by a day due to anticipated winds in Texas, it isn’t holding Shatner’s fans back from gearing up for the liftoff. Late last week, a user tweeted

Inside a huge crater in Israel’s sun-baked Negev desert, a team wearing space suits ventures forth on a mission to simulate conditions on Mars. The Austrian Space Forum has set up a pretend Martian base with the Israeli space agency at Makhtesh Ramon, a 1,600 feet (500m) deep, 25 miles (40km) wide crater. The six

Singapore now has robots on its streets to carry out safety-related surveillance of citizens. The patrol robots, named Xavier, have been programmed to roam around the streets of Singapore and detect “undesirable social behaviour.” The robots move amidst people on regular pathways. They have been fitted with seven cameras to detect any anomaly in proper
