One of the most intense cosmic shockwaves has been observed in Stephan’s Quintet, a group of galaxies located approximately 290 million light-years from Earth. The event was triggered by the galaxy NGC 7318b colliding with four neighbouring galaxies at an estimated velocity of two million mph (3.2 million kmph). The collision produced a shock front

Emily Calandrelli, an advocate for STEM education and an aerospace engineer, made history on November 22, 2024, as the 100th woman to travel to space. The flight, conducted by Blue Origin’s New Shepard rocket, took off and landed at the company’s West Texas facility. This suborbital journey carried six civilian passengers and reached a peak

NASA’s Hubble Space Telescope has provided new insights into the young star FU Orionis, located in the constellation Orion. Observations have uncovered extreme temperatures in the inner region of its accretion disk, challenging current models of stellar accretion. Using Hubble’s Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph, astronomers captured far-ultraviolet and near-ultraviolet spectra, revealing

A recent NASA-funded study has observed findings about the molecular processes that might have shaped the origins of life on Earth. Research published in Nature Communications suggests that ribonucleic acid (RNA), a molecule believed to have predated DNA, exhibits no inherent bias in producing the left- or right-handed versions of amino acids. This challenges long-standing

The Federal Aviation Administration (FAA) has issued a draft environmental assessment (EA) proposing an increase in SpaceX’s annual Starship launches. The assessment, published on November 20, outlines the possibility of raising the current limit of five launches per year from Starbase in South Texas to 25 by 2025. This draft also includes approvals for 25

The pursuit of understanding dark matter, which comprises 85 percent of the universe’s mass, could take a significant leap forward with a nearby supernova. Researchers at the University of California, Berkeley, led by Associate Professor of Physics Benjamin Safdi, have theorised that the elusive particle known as the axion might be detected within moments of

Intelligent extraterrestrial civilisations might be utilising stars as massive interstellar vehicles to explore the galaxy, according to a theory proposed by Clement Vidal, a philosopher at Vrije Universiteit Brussel in Belgium. His research suggests that alien species could potentially accelerate their binary star systems to traverse vast cosmic distances. While such a concept is purely

Efforts to create a comprehensive map of all human cells have taken a significant leap forward. Researchers associated with the Human Cell Atlas (HCA), a global scientific consortium, have released over 40 studies detailing critical progress in mapping the 37 trillion cells that make up the human body. These findings, published on 20 November in

A new study highlights the critical role of the Irminger Sea, located off southeastern Greenland, in maintaining the strength of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC, a global ocean conveyor belt, is crucial for regulating Earth’s climate, particularly in the Northern Hemisphere. According to research led by Dr Qiyun Ma, a postdoctoral researcher

NASA‘s Perseverance rover, currently exploring Mars’ Jezero Crater, has detected carbon-based molecules that may hint at ancient life on the Red Planet. These findings, reported last summer, were made using SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals), an advanced instrument capable of identifying potential organic compounds. While the discovery has

At the Supercomputing Conference or SC2024, NASA’s Associate Administrator for the Science Mission Directorate, Nicola Fox, detailed new computational tools intended to advance space science. NASA plans to employ a large language model across its science divisions, bolstered by foundation models tailored to Earth science, heliophysics, astrophysics, planetary science, and biological and physical sciences. This

A study conducted at the University of Birmingham has identified the precise shape of a single photon, reshaping how interactions between light and matter at the quantum level are understood. The study detailed in Physical Review Letters tells us how photons, or particles of light, are emitted and influenced by their surroundings, offering possibilities for

A 2,600-year-old inscription engraved on a monument in Turkey, known as Arslan Kaya or “lion rock,” has been deciphered, according to research by Professor Mark Munn of Pennsylvania State University. This ancient carving, which has endured significant damage from weathering and looting, contains references to Materan, a goddess revered by the Phrygians, an ancient civilisation

SpaceX is slated to launch its gargantuan Starship rocket on Tuesday out of South Texas, a key test that is expected to include a guest visit from President-elect Donald Trump. The sixth major test mission comes as SpaceX Chief Executive Officer Elon Musk is heavily engaged in transition planning for Trump’s second administration. Musk, who

A breakthrough in biosensor technology could enable the real-time monitoring of stress and alertness in drivers and pilots. Developed by researchers from the National University of Singapore and Tsinghua University, the device, integrated into seatbelts, tracks heartbeat and respiration without needing direct contact with the skin. This innovation, detailed in Nature Electronics, promises to enhance

Archaeologists have uncovered a remarkable 2,000-year-old Roman knife handle in Northumberland, England. The discovery, made in the River Tyne near Corbridge Roman Town, features a detailed depiction of a gladiator. This unique find sheds light on the influence and popularity of gladiators across the Roman Empire, including its farthest reaches in Britain. As per a

A new artificial intelligence (AI) tool, Earth Copilot, has been introduced by NASA in collaboration with Microsoft to make Earth-related scientific data more accessible. Designed to summarise NASA’s extensive geospatial information, the AI-powered chatbot aims to simplify complex datasets and answer user queries with ease. By addressing questions like the environmental impact of events or

A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This survey, conducted with the Dark Energy Spectroscopic Instrument (DESI) at the Mayall Telescope in Arizona, identified over 2,500 black holes in dwarf galaxies—more than triple

A study by the European Synchrotron Radiation Facility (ESRF) suggests that early Homo species may have experienced extended childhoods well before significant brain enlargement, challenging longstanding evolutionary assumptions. The findings are based on the dental development of a nearly complete sub-adult Homo skull, unearthed at the Dmanisi site in Georgia and dated to 1.77 million

The much-anticipated Tamil drama Parachute, starring Krishna and Kishore, is set to stream on Disney+ Hotstar from November 29. Directed by Sridhar K, the film introduces a heartfelt narrative about childhood, familial relationships and the challenges of parenthood. Alongside the lead actors, the ensemble cast includes Kani Thiru, Kaali Venkat and child artists Shakthi Ritwik
