All About Asteroid 2025 PN7, Earth's New Quasi-Moon
2025 PN7 is a small, 18-36 meter wide space rock that's been dubbed Earth's "second moon" due to its unique orbit.

Astronomers Detect Hints Of Hidden Earth-Sized Planet Beyond Neptune
Astronomers propose the existence of ‘Planet Y’, a hidden Earth-size planet that may orbit closer than the theorized ‘Planet Nine’. Based on Kuiper Belt object patterns, the study suggests a rocky world influencing orbital tilts. Experts remain divided, but upcoming sky surveys could soon confirm or rule out its existence.

Starlink Satellites Falling To Earth Raise Fears Of Space Junk "Chain Reaction"
While SpaceX's Starlink network has revolutionised global connectivity, its rapid expansion adds to growing congestion in orbit.

Astronomers Detect Smallest Known Clump of Pure Dark Matter Using Gravitational Lensing
Astronomers using a global radio telescope array have detected the smallest known pure dark matter clump, roughly a million times the Sun’s mass. Found through a faint gravitational distortion in an Einstein ring, it offers new insight into how dark matter halos form across the universe.

Rising Satellite Traffic in Low Earth Orbit Sparks Collision Risk Concerns
A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coo...

Reflect Orbital Plans to Light Up Parts of Earth Where Sunlight Does Not Reach by April 2026
Reflect Orbital recently filed an application with the US FCC Space Bureau seeking permission to test launch its Earendil-1 non-geostationary orbit satellite. With this, the startup plans to begin redirecting the light emitted by the Sun with the help of glass-like satellites to dimly lit parts of the Earth. After closing its Series A round earlier...

First Supermoon Of The Year Is Approaching. Here's What To Know
The moon will appear slightly larger and brighter Monday night during what's known as a supermoon.

Hidden Asteroids Near Venus Pose Long-Term Threat To Earth, Study Reveals
Some of the asteroids could intersect Earth's path within a few thousand years, posing a collision risk.

Asteroid 2024 YR4 Raises Concerns Over Moon Impact; Scientists Consider Nuclear Defence
Asteroid 2024 YR4 is drawing global attention as a possible lunar impactor in 2032. Though the chances of Earth impact have dropped, a collision with the Moon could still create dangerous orbital debris. Scientists stress preparedness, exploring deflection missions and nuclear defense strategies.

Earth’s Oxygen Explains Mysterious Rust Formation on the Moon
Despite lacking air and water, the Moon hosts hematite—an oxidized iron mineral. Scientists discovered Earth’s escaping oxygen drives this rusting process during the Moon’s passage through the magnetotail. Observations from Chandrayaan-1 and NASA’s Lunar Reconnaissance Orbiter confirm hematite patches where Earth wind suppresses hydrogen an...

Dead Star's Supernova Explosion Could Be Visible From Earth During Daytime, Study Predicts
When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

New Quasi-Moon Discovered Orbiting Near Earth, Unnoticed For 60 Years
This quasi-moon likely remained unnoticed for six decades because of its faintness and limited visibility.

New 'Quasi-Moon' Discovered in Earth Orbit May Have Been Hiding There for Decades
Astronomers have identified asteroid 2025 PN7 as a possible quasi-moon of Earth, trailing our planet for nearly 70 years. At just 62 feet wide, it is the smallest and least stable quasi-satellite detected so far. Researchers believe advanced observatories like the Vera Rubin Observatory could uncover more hidden companions in Earth-like orbits

NASA’s Artemis II Astronauts Will Double as Test Subjects for Deep Space Health Research
NASA’s Artemis II mission will send astronauts beyond low Earth orbit as both scientists and volunteer test subjects. The crew will conduct health, radiation, and lunar studies, providing vital data to protect future explorers. Results will guide safety protocols for lunar and Mars missions, advancing human readiness for long-duration deep space ...
