A recent discussion among experts highlights a critical gap in the United States’ capacity for in-space rescues. As human spaceflight missions become more common, the absence of a dedicated “space rescue service” raises concerns about the safety of astronauts in distress. The historical lessons from missions like Apollo and the space shuttle seem to have

In the next few weeks, NASA will embark on a significant mission to Europa, the fourth-largest moon of Jupiter. Named Europa Clipper, this spacecraft is designed to search for potential signs of life. While Mars is often the focal point in the quest for life beyond Earth, Europa presents a promising alternative due to its
An unexpected discovery concerning gene regulation has earned Victor Ambros from the University of Massachusetts Chan Medical School and Gary Ruvkun from Harvard Medical School the 2024 Nobel Prize in physiology or medicine. The duo’s research identified small RNA segments, known as microRNAs, which play a significant role in regulating protein production in the body.
The Draconid Meteor Shower, known for its connection to the constellation Draco, is set to peak on October 8th and 9th this year. This annual meteor shower provides a rare opportunity for skywatchers to witness meteors during the evening hours. The constellation Draco lies in the northern sky, making the shower visible throughout the night.
Recent research has provided a deeper understanding of the mysterious craters appearing in Siberia. These craters, some as deep as 160 feet (50 meters) and wide as 230 feet (70 meters), form when thawing permafrost triggers sudden methane gas explosions. The permafrost thaw causes cracks, releasing methane gas stored deep underground, leading to these dramatic
NASA has chosen two mission proposals to further investigate X-ray and far-infrared wavelengths, marking the start of a new class of astrophysics missions. These missions fall within NASA’s Explorers Programme and have been allocated $5 million each for a 12-month concept study. A final decision will be made in 2026, with the selected mission launching
A fascinating study suggests that Mount Everest, standing at 29,031.69 feet (8,848.86 m), may be taller than expected due to an ancient river “capture” event. This geological phenomenon occurred approximately 89,000 years ago and involved a river located around 46 miles (75 kilometres) from the mountain. Researchers propose that the erosion resulting from this event
A recent study by astrophysicists suggests that advanced alien civilisations might only have a thousand years before their planets become uninhabitable due to climate change. This alarming finding stems from simulations exploring the trajectory of technological growth and energy consumption of these hypothetical societies. Even those relying on renewable energy could face dire consequences, as
NASA has shut off one of Voyager 2’s scientific instruments to preserve its remaining power as it journeys through interstellar space. The spacecraft, launched on 20 August 1977, is currently positioned 12.8 billion miles from Earth and is exploring beyond the solar system. Since leaving the heliosphere on 5 November 2018, Voyager 2 has been
October offers a fascinating opportunity for skywatchers with a new comet making its appearance and several planets visible throughout the month. A particularly intriguing comet, known as C/2023 A3 (Tsuchinshan-ATLAS), will grace the evening skies after October 14. It remains to be seen whether it will be the brightest comet of the year, as it
On 29th September, Earth captured a temporary new companion, an asteroid named 2024 PT5. This near-Earth object, roughly the size of a bus at 33 feet wide, has entered Earth’s orbit for 57 days before it’s expected to resume its path around the sun. While the term “minimoon” sounds exciting, 2024 PT5 is far too
Indian scientists recently made a fascinating discovery: the global COVID-19 lockdowns of 2020 affected not only Earth but also the Moon’s temperature. A study published in the Monthly Notices of the Royal Astronomical Society: Letters found that lunar nighttime temperatures dropped by 8-10 Kelvin during the strict lockdown period between April and May 2020. Led
The annular solar eclipse on October 2, 2024, will be a remarkable celestial event. When the moon passes between the Earth and the sun, it will create a ring of fire visible from parts of the Southern Hemisphere. But how fast will this event unfold across the planet? Why the Eclipse Speed Varies The speed
October 2024 brings an exciting celestial opportunity for Bengaluru residents as a rare comet, known as Comet C/2023 A3, makes its appearance in the city’s skies. This spectacular object was first spotted in 2023 and has now returned, offering early morning views in the initial days of the month. Spotting the Comet in Early October
Scientists have recently uncovered a rare geological event occurring beneath the Central Anatolian Plateau in Türkiye. This phenomenon, known as “crustal dripping,” has been shaping the Konya Basin, sparking intrigue among geologists. Satellite imagery and detailed geological data have played a significant role in revealing the intricate process behind this event. The Process Behind Crustal
Researchers have discovered an innovative method to help tackle climate change: burying wood underground. A 3,775-year-old log found in Canada has shown that wood can preserve its carbon content for thousands of years when buried in the right conditions. This discovery, led by climate scientist Ning Zeng, suggests a low-cost, scalable way to lock carbon
SpaceX‘s Crew-9 mission successfully reached the International Space Station (ISS) on September 29, 2024. The NASA astronaut Colonel Nick Hague and Russian cosmonaut Aleksandr Gorbunov boarded the Crew Dragon capsule, named Freedom. After launching from Florida’s Cape Canaveral Space Force Station on September 28th, the crew completed a one-day orbital journey before docking at 5:30
NASA scientists have determined that Earth will capture a second moon on Sunday, 29th September 2024. This small asteroid, named 2024 PT5, typically orbits the sun as part of the Arjuna asteroid belt. Unlike our long-term lunar companion, which has orbited Earth for over 4 billion years, this temporary second moon will only stay with
The European Space Agency (ESA) is preparing to launch a unique satellite in 2027, designed specifically to study how satellites break apart upon reentry into Earth’s atmosphere. This mission, named DRACO (Destructive Reentry Assessment Container Object), will be an important step in ESA’s effort to develop technology that limits the creation of space debris. ESA
In May 2024, a remarkable geomagnetic storm, also known as solar storm, impacted Earth, resulting in vibrant auroras that captivated observers worldwide. These stunning natural displays occur when eruptions of solar plasma, known as coronal mass ejections, collide with Earth’s magnetic field. While these events are a visual delight, they also raise significant questions about
