NASA’s Hubble Observes Rare Blue Lurker Star with Unusual Evolution in M67 Cluster
NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue lurker” in the M67 star cluster. Located 2,800 light-years away, this star is part of a triple-star system and has an unusual evolutionary history. The blue lurker’s accelerated spin, taking just four days, contrasts with the typical rotation of Sun-like...

Pixxel to Launch India’s First Private Satellite Network, Eyes $19 Billion Market
Pixxel is set to launch three of its six hyperspectral imaging satellites aboard a SpaceX rocket from California on Tuesday. The launch is scheduled to take place at the Vandenberg Space Force Base at around 10:45 a.m. Pacific Time (1845 GMT) on Tuesday - just after midnight the next day in India - subject to final approvals.

China Conducts Five Rocket Engine Tests in a Day, Advancing Space Projects
On January 2, China tested five rocket engines in Beijing and Hebei Province. These tests included hydrogen-oxygen and methane-based engines for various applications, such as lunar missions and deep-space exploration. The trials mark a significant step in China’s efforts to enhance its space programmes. CASC’s engineers have highlighted the suc...

The Science Of Warmth: How Fleece Keeps You Comfortable In Cold Weather
When the frost bites and the winds howl, nothing beats the comforting embrace of fleece. But what makes this fabric so good at keeping us cosy during chilly days? Let’s unravel the science behind fleece and how it is the go-to fabric for winter wear.

Supermassive Black Hole Flashed Twice in a Rare Event, Scientists Explain the Reason
In a galaxy 408 million light-years away, the black hole ASASSN-22ci consumed a star from a binary system, producing a rare double-flash tidal disruption event (TDE). First observed in February 2022, a second flare occurred 720 days later, possibly caused by Hills capture. Researchers anticipate a third flare in early 2026, offering unprecedented i...

Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere
Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

ISRO Cowpea Seeds Successfully Germinate in Space: Everything You Need to Know
ISRO marked a significant achievement with the successful germination of cowpea seeds in space, conducted as part of the CROPS experiment by the Vikram Sarabhai Space Centre (VSSC). Launched aboard the PSLV-C60 POEM-4 platform, the experiment aimed to study plant growth in microgravity, a key factor for future space missions. The seeds sprouted wit...

SpaceX Calls off Falcon 9 Launch of Four MicroGEO Satellites at Last Second
SpaceX’s planned launch of four MicroGEO satellites was halted at the final second on December 21, 2024. The Falcon 9 rocket, set to lift off from Cape Canaveral, was forced into a scrub after the engines ignited at T-0 seconds due to an unspecified technical issue. The satellites, developed by Astranis, were intended to provide broadband service...

Boeing Starliner Astronauts’ Return Delayed Until March 2025 Following SpaceX Delay
NASA astronauts Barry "Butch" Wilmore and Sunita Williams, aboard the Boeing Starliner spacecraft, will remain on the International Space Station (ISS) until March 2025 due to a delay in the SpaceX Crew-10 mission. The launch of Crew-10 has been postponed to allow for the completion of a new Crew Dragon capsule. This delay extends their stay from t...

SWOT Satellite Reveals Key Insights on Ohio River Basin Lakes and Reservoirs
The SWOT satellite, a joint NASA-CNES mission, has provided new insights into the Ohio River Basin’s lakes, reservoirs, and water movement. Observations show water level changes between 1,600 feet and 330 feet, offering hydrologists critical insights into river discharge and freshwater availability. The SWOT satellite captures comprehensive water...

Mars Dust Storms May Be Predictable Based on Surface Heating Patterns
A new study suggests warm days on Mars often precede dust storms, with researchers analysing data from NASA's Mars Reconnaissance Orbiter. The findings show 78% of storms correlate with increased solar heating, particularly in northern regions of the planet. Scientists have developed an algorithm predicting certain storm types with 64% confidence, ...

Arctic Ocean Likely to Experience Ice-Free Day by 2027, Study Warns
A study published in Nature Communications predicts the Arctic Ocean could face its first ice-free day as early as 2027, marking a critical environmental milestone. Conducted using 11 climate models and 366 simulations, the research highlights the urgent need for emission reductions. The loss of sea ice in the Arctic exacerbates global warming thro...
