Oceans Were Once Green, Could Change Colour Again: Study
Nearly three fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth's oceans were once green, in a study published in Nature.

Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...

ISRO's POEM-4 Re-Enters Earth's Atmosphere
The safe re-entry of POEM-4 is yet another accomplishment of ISRO's commitment to containing the growth of space debris.

Two New Exoplanets Found Orbiting a Star in Draco Constellation
Astronomers have identified two exoplanets, TOI-1453 b and TOI-1453 c, orbiting a star 250 light-years away in Draco. The planets, a super-Earth and a sub-Neptune, were detected using NASA’s TESS satellite and the HARPS-N spectrograph. TOI-1453 b is a rocky planet orbiting close to its star, while TOI-1453 c is twice Earth’s size and may have a...

Mysterious Light Spiral Over Europe Traced to SpaceX Falcon 9 Reentry
On March 24, a glowing spiral appeared in the night sky across parts of Europe, including the UK, Sweden, Croatia, Poland, and Hungary. The formation lasted for about 12 minutes before fading. Experts confirmed it was caused by a SpaceX Falcon 9 rocket reentering Earth's atmosphere after completing its mission. The phenomenon resulted from frozen f...

James Webb Telescope Captures Neptune’s Auroras in Stunning Detail
The James Webb Space Telescope has provided the first-ever direct images of Neptune’s auroras, revealing surprising details about the ice giant’s atmosphere. Unlike auroras on Earth, Jupiter, or Saturn, Neptune’s auroras appear across unexpected locations due to its tilted and offset magnetic field. Scientists also detected the presence of H...

NASA to Launch Three Rockets in Alaska to Study Auroral Substorms’ Impact
NASA is conducting a rocket experiment from Poker Flat Research Range in Alaska. Three rockets will launch within a three-hour window to study how auroral substorms influence the Earth's upper atmosphere. Scientists will observe whether auroras drive vertical convection or if acoustic-buoyancy waves spread their energy over a wider region. Vapour t...

NASA’s EZIE Satellites Begin Mission to Study Auroral Electrojets and Space Weather
NASA’s Electrojet Zeeman Imaging Explorer (EZIE) mission has been launched aboard a SpaceX Falcon 9 from Vandenberg Space Force Base. The trio of small satellites will map auroral electrojets, powerful currents in Earth’s atmosphere linked to solar storms. Their data will enhance space weather prediction models and help understand planetary mag...

Ancient Volcanoes May Have Helped Create Perfect Balance For Life On Earth
Latest findings suggest that the Earth's atmosphere went through a sequence of oxygenation episodes fueled by geological and biological interactions rather than a single event.

Vernal Equinox 2025: Date, Time, and the Science Behind the Event
The vernal equinox 2025 is set for March 20 at 09:01 UTC, marking the astronomical start of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. This event occurs due to Earth’s axial tilt aligning with its orbit, resulting in nearly equal hours of daylight and night across the globe. While the equinox does not bring perfectly...

Astronaut Captures Rare ‘Gigantic Jet’ Lightning Extending 50 Miles Above Earth
A rare ‘gigantic jet’ lightning was captured by an astronaut aboard the ISS on November 19, 2024. This massive bolt extended nearly 50 miles into the atmosphere, likely originating from a thunderstorm near New Orleans. The image, later discovered in NASA’s archives, highlights an unusual lightning event that travels upwards instead of strikin...

Private Venus Mission Plans to Retrieve Cloud Samples for Life Research
A privately-led space mission is being developed to retrieve and analyse cloud samples from Venus. Scientists believe the planet’s sulfuric acid clouds might sustain organic molecules necessary for life. The mission, named Morning Star, involves deploying probes to collect mist from Venus' atmosphere. The collected samples would be returned to Ea...

Curiosity Rover Finds Evidence of Liquid Water on Mars, Expanding Habitability Timeline
Reports from NASA’s Curiosity rover reveal evidence of ancient liquid water on Mars, challenging previous models. Images from Gale Crater show wave-like ripples, similar to Earth’s lakebeds. Scientists suggest the findings indicate Mars once had a denser atmosphere, which allowed liquid water to exist longer than previously believed. This disco...

'MACE' Observatory Detects 'Blast From The Past' Way Before Earth Was Born
Scientists from the Bhabha Atomic Research Center, Mumbai part of the Department of Atomic Energy, have detected a distant explosion from a galaxy, of what is also called a Gamma Ray flare.

Newly Confirmed Super-Earth HD 20794 d May Support Life in Habitable Zone
A super-Earth, HD 20794 d, has been confirmed within a habitable zone 20 light years from Earth. The planet, first detected in 2022, has a mass six times that of Earth and orbits a sun-like star. Although its elliptical orbit affects temperature stability, its potential to sustain liquid water makes it a key target for upcoming space missions. Scie...
