NASA’s latest infrared space telescope, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), is set for launch on 28th February. The mission, valued at $488 million, will take off from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. Designed to scan the entire sky in

The origins of dog domestication have been a topic of debate among scientists, with theories suggesting various evolutionary processes led to the transformation of wolves into the domestic dogs seen today. A new study has indicated that early wolves may have chosen to stay near humans due to the availability of food scraps, potentially leading

Our environment continues to grapple with plastic pollution, with microplastics infiltrating the air, food, and water. Scientists are actively seeking methods to break down this persistent material. A new development has identified bacteria in wastewater that can degrade polyethylene terephthalate (PET), a plastic widely used in packaging and textiles. The discovery has raised hopes of

A striking image of the Tarantula Nebula has been captured by the NASA/ESA Hubble Space Telescope, showcasing a vast cosmic landscape filled with swirling gas and dust. Situated around 160,000 light-years away in the Large Magellanic Cloud, this nebula is known as one of the most active star-forming regions in the universe. The image reveals

Greenland’s ice sheet is heading towards an irreversible tipping point that could lead to catastrophic consequences, as warned by climate scientists. The immense sheet has been losing ice at an unprecedented rate, with estimates indicating a loss of around 33 million tons per hour. A global temperature rise of just 2 degrees Celsius could trigger

An unexpected spiral structure has been identified at the edge of the solar system, potentially altering current understanding of the Oort Cloud. This discovery has emerged from a computational model developed using data from comets and gravitational influences. The Oort Cloud, a distant shell of icy bodies, has long remained an enigma due to its

An elliptical galaxy located 88 million light-years from Earth has been observed displaying unusual characteristics, with astronomers identifying it as a cosmic predator. The latest images captured by the Very Large Telescope (VLT) at the European Southern Observatory (ESO) indicate that the galaxy, designated NGC 3640, has a history of consuming smaller galaxies and may

A decline in global ocean evaporation has been identified over the past decade, despite rising sea surface temperatures. This shift challenges established climate models, which have long linked higher temperatures to increased evaporation. The unexpected trend was observed through satellite data analysis, revealing that evaporation rates started decreasing after 2008. Researchers suggest that changing atmospheric

Extreme rainfall in Arabia was five times more intense 400 years ago, as indicated by recent climate reconstructions. The data suggests that the region, currently defined by arid desert, once had significantly higher precipitation levels, resembling a lush savannah. The findings highlight the necessity for improved climate preparedness as urbanisation expands in the region. Study

The United States Space Force has unveiled a never-before-seen image of its X-37B space plane in orbit. The photograph, released on February 20, was captured by an onboard camera as the vehicle conducted experiments above the African continent. Visible in the image are one of the space plane’s solar panels on the left side and

detected, leaving astronomers searching for answers. The sudden burst of energy was identified while analysing archival data from NASA’s Chandra X-ray Observatory, revealing a cosmic event that occurred more than 20 years ago. The flash, designated XRT 200515, originated from the Large Magellanic Cloud (LMC), a satellite galaxy of the Milky Way, situated approximately 160,000

A batch of 23 Starlink satellites was launched by SpaceX aboard a Falcon 9 rocket from Cape Canaveral Space Force Station on February 21. The mission, which took place at 10:19 a.m. EST, marked a significant milestone for the company, as it was the 450th flight of a Falcon-series rocket. Clear weather conditions allowed for

A new robotic system capable of planetary exploration through tethered jumping has been developed by researchers at the Robotics and Mechanisms Laboratory (RoMeLa) at the University of California, Los Angeles (UCLA). The robot, named SPLITTER (Space and Planetary Limbed Intelligent Tether Technology Exploration Robot), has been designed as a modular, multi-robot system composed of two

The Indian Institute of Technology Madras (IIT Madras) and the Indian Space Research Organisation (ISRO) have successfully developed and booted an aerospace-grade semiconductor chip, marking a significant step towards self-reliance in space technology. The chip, named ‘IRIS’ (Indigenous RISCV Controller for Space Applications), has been designed based on the SHAKTI processor and is intended for

The James Webb Space Telescope (JWST) has been allocated emergency observation time to study asteroid 2024 YR4, which has been classified as potentially hazardous. The space rock was identified in December 2024 and has been placed on the asteroid watch list due to its estimated 2.3% chance of colliding with Earth in December 2032. The

An increase in seismic activity has been recorded at Mount Spurr, a stratovolcano located 124 kilometres west of Anchorage, Alaska. Over the past ten months, small earthquakes have been detected, with a noticeable rise in activity observed in recent weeks. Reports indicate that the earthquakes, which were initially concentrated near the summit, have shifted towards

Two mysterious light sources detected on the outskirts of the Large Magellanic Cloud have been identified as previously unknown supernova remnants. The discovery was made using the European Space Agency’s X-ray observatory, XMM-Newton after observations revealed unexpected X-ray emissions. Supernova remnants are formed when massive stars explode, creating shock waves that ionise and compress surrounding

The behaviour of the universe on the largest scales is being examined through weak gravitational lensing, a method that may confirm or challenge the long-standing Cosmological Principle. This principle, which asserts that the universe is both homogeneous and isotropic, underpins the Standard Model of Cosmology. If inconsistencies are detected, fundamental assumptions about the universe’s structure

A significant solar storm that occurred in May 2024 led to the formation of two temporary radiation belts around Earth, as confirmed by satellite data. The discovery was made when a dormant satellite resumed operations after months of inactivity. The storm, which was among the most intense geomagnetic disturbances since 1989, resulted in widespread auroral

A significant increase in global rocket launches was observed in 2024, with 259 recorded liftoffs. This marked the fourth consecutive year of growth in spaceflight activity, with launch attempts occurring approximately every 34 hours. Multiple factors contributed to this rise, including increased commercial satellite deployments, national security initiatives, and a growing emphasis on independent launch
