Moon Calling: NASA and Nokia to launch the first cellular network in Space; Here’s all you need to know
NASA and Nokia are set to deploy the first mobile network on the Moon as part of the IM-2 mission. Utilizing Earth-based cellular technology, the network aims to support high-definition video streaming and communication on the lunar surface, setting the stage for future lunar missions under NASA’s Artemis program.
Iron mineral reason for Mars's red colour, study suggests; hints planet was once habitable
Research suggests Mars's red hue may be due to ferrihydrite, an iron oxide formed in cool water, implying past habitability. Data from Mars missions and lab simulations support this theory, which NASA's Perseverance rover will further investigate, aiming to uncover Mars's ancient climate.
Seven-planet parade to be visible across the sky this week: How, when & where to watch in India
A rare celestial event will unfold on 28 February 2025 as all seven planets—Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune—align in the night sky. This planetary parade, last seen in 2004, won’t occur again until 2040. Visible from across India, the spectacle will be best observed 45 minutes after sunset. While some planets can be seen with the naked eye, others require binoculars or telescopes. Skywatchers are advised to find dark, clear locations for the best view.
Astronomers spot the largest cosmic giant of its kind in the distant universe
Astronomers have discovered an enormous radio jet stretching over 200,000 light-years from a quasar in the early universe, offering rare insights into cosmic evolution. The jet, the largest of its kind from this era, was detected using powerful radio telescopes, overcoming challenges posed by cosmic background radiation. This finding confirms that even smaller black holes in the young universe could produce vast energy outflows, shaping galaxies and spreading magnetism far beyond their host systems.
Another bat virus discovered from China—Here’s what makes HKU5-CoV-2 different from COVID-19
A team of Chinese researchers has discovered a new bat coronavirus, HKU5-CoV-2, which has the potential to infect human cells. The virus, linked to the same family as MERS, was found to bind to human ACE2 receptors, though with lower efficiency than SARS-CoV-2. While no human cases have been reported, scientists stress the need for ongoing monitoring. Experts caution against exaggerating its pandemic potential, highlighting existing immunity and antiviral treatments as key factors in mitigating future risks.
Study suggests origin of elasticity could lie in how molecules interact under stress
A study suggests elasticity in objects originates from interactions between molecules in flexible materials. Researchers from The University of Queensland found that energy stored in these interactions allows materials to regain their shape after deformation. This insight could lead to the development of new, elastically flexible crystals for use in spacecraft and electronic devices.
mRNA vaccine against tuberculosis shows efficacy in mice, results pave way for larger trials
Australian researchers have developed a new mRNA vaccine for tuberculosis, showing effective results in mice. The vaccine enhances immunity and offers better long-term protection compared to the traditional BCG vaccine, paving the way for future clinical trials and potentially improved TB control.
Moon or Mars? NASA's future at a crossroads under Trump
Is NASA still Moonbound, or will the next giant leap mean skipping straight to Mars? Though Artemis was conceived in President Donald Trump's first term, he has openly mused about bypassing the Moon and heading straight to Mars -- a notion gaining traction as Elon Musk, the world's richest person and SpaceX's owner, becomes a key ally and advisor.
How does space travel affect astronaut health?
Space travel poses significant challenges to human health due to microgravity, radiation exposure, and psychological stress. Microgravity leads to fluid shifts, muscle atrophy, and bone loss, while radiation increases cancer risk and damages DNA. Isolation affects mental well-being. Recovery varies, with longer missions causing lasting effects.
Germany-based VIK-Composite to set up facility in India, partners with JBI Aerospace
JBI Aerospace and VIK-Composite GmbH partner to set up an advanced manufacturing facility in India. The facility will cater to aerospace, space, wind energy, and defence sectors, aiming to reduce costs, shorten lead times, and enhance local composite manufacturing capabilities.

Would a mini black hole vaporise you? Scientists break it down
A new study delves into the mind-bending question: what if a tiny primordial black hole passed through a human body? Scientists examine the impact of tidal forces and shockwaves, revealing that while such an encounter could be lethal, the odds of it happening are astronomically low. The research sheds light on the theoretical existence of these ancient black holes, their possible interactions with Earth, and why they remain one of the universe’s most elusive mysteries.
Microbes in microgravity: Indian students' nanosatellite aims to help astronauts stay healthy in space
India’s first microbiological nanosatellite, RVSAT-1, launched aboard ISRO’s PSLV C-60 in December 2024, is a pioneering student-led mission studying gut bacteria in space. Developed by Bengaluru’s RV College of Engineering, it examines bacterial growth in zero gravity, offering insights into astronaut health and antibiotic resistance. The mission’s success highlights the potential of student innovation in space research, with data set to benefit ISRO, academia, and future space missions.
Is your cancer risk written in your genes? Study explores pre-birth risk factors
A new study suggests that cancer risk may be shaped before birth, challenging the long-held belief that genetic mutations acquired over time are the primary cause. Researchers at the Van Andel Institute found that subtle differences in early development, influenced by epigenetics, could determine susceptibility to cancer later in life. The study identified two distinct gene expression patterns that affect cancer risk, opening new possibilities for early diagnosis and prevention strategies.
Scientists stumble upon a strange ‘Super-Earth’; Here's what makes it so unusual
Scientists from Oxford University have confirmed the discovery of HD 20794 d, a “super-Earth” exoplanet located 20 light-years away, which may have the conditions needed to support life. Despite its position in the habitable zone, the planet’s elliptical orbit raises questions about its atmosphere’s ability to sustain life. Future missions will study its atmosphere in search of biosignatures, advancing the search for extraterrestrial life.
Indian researchers discover new exoplanet TOI-6038A b. Here's all about it
Indian researchers have discovered a dense sub-Saturn exoplanet, TOI-6038A b, which is 78.5 times the mass of Earth. This exoplanet orbits a bright, metal-rich F-type star every 5.83 days. The detection, involving PARAS-2 spectrograph, provides valuable insights into planetary formation and evolution, highlighting India's advancements in astronomical instrumentation.
Moon to the rescue? Scientists say Earth’s ‘bodyguard’ could absorb deadly 'city-killer' asteroid's impact
Asteroid 2024 YR4, a potential “city-killer,” has a small chance of hitting Earth in 2032—but scientists say it might strike the Moon instead. Measuring up to 90 metres wide, the asteroid could create a dramatic lunar impact, though experts insist the risk to Earth remains low. While some warn that deflecting it in time may be difficult, NASA and global space agencies continue monitoring its path. With new observations, its threat level may soon be reassessed.
