NASA on Thursday (February 19, 2026) released a sweeping report on Boeing’s botched Starliner mission that left two astronauts stuck on the International Space ​Station for nearly a year, detailing communication breakdowns and “unprofessional behavior” as the agency and its longtime contractor struggled to agree on ‌how to safely return the crew to Earth. NASA...

Observations and measurements made by India’s maiden solar mission, Aditya-L1, have helped to decode the unusual dawn-time geomagnetic disturbances during strong solar storms. Geomagnetic storms are large disturbances in Earth’s magnetic field caused by changes in the solar wind- a continuous flow of charged particles released from the Sun. “When sudden increases or decreases in...

NASA on Thursday (February 19, 2026) said it successfully rehearsed the launch of its massive SLS rocket, which will send astronauts around the Moon for the first time in over 50 years. Technical problems in early February cut short an earlier so-called wet dress rehearsal of the launch of the Artemis 2 mission. But on...

Helen Keller, the American author and activist who was deaf and blind, became an international symbol of human potential. She wrote, “Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.” Optimism can be defined as maintaining positive expectations for the future. It is a human trait that has...

The story so far: In 1999, California-based Nvidia Corp. marketed a chip called GeForce 256 as “the world’s first GPU”. Its purpose was to make videogames run better and look better. In the 2.5 decades since, GPUs have moved from the discretionary world of games and visual effects to becoming part of the core infrastructure...

The Science Quiz: The science hidden in proverbs and idioms 1 / 6 | Name this hydrocarbon. It’s the reason “one bad apple spoils the bunch”: as an apple ripens, it releases more of this compound, which causes nearby fruit to ripen faster.

The linear no-threshold (LNT) model and the ALARA principle have served as the conceptual and operational foundations of the global radiation protection framework for many decades. The LNT model is a risk estimation framework that says any amount of ionising radiation, no matter how small, carries some risk of causing harm, especially cancer. In other...

– Gayatri Chandrashekar Shrubs and trees often flower and fruit more on the sunlit side because the planet’s energy budget on that side is different. Sunlit leaves capture more usable light so they photosynthesise more and make more sugars and starch. Buds and young fruits need that carbon supply to form and grow. On the...

When a sufficiently massive star runs out of fuel, its core collapses and triggers a supernova, a dramatic explosion that scatters the star’s outer layers into space. But scientists have long suspected that sometimes, the explosion fails and instead of a supernova, the star just… disappears. In a recent paper in Science, astronomers have reported...
