This Asteroid Could Hit Earth In 2032, Threatening To Wipe Out A City
NASA has detected an asteroid called 2024 YR4, which has a 1 in 83 chance of impacting Earth in 2032, potentially releasing 8 megatons of energy and devastating a major city, although it's too small to end human civilization.

New Study Finds Active Lunar Tectonics, Challenges Moon’s Dormancy
A recent study published in The Planetary Science Journal reveals that the moon is still experiencing tectonic activity. Scientists identified 266 small ridges on the far side of the moon, formed within the last 160 to 200 million years. The study suggests these ridges result from geological forces like lunar shrinking and orbital shifts. The findi...

Mysterious Interstellar Object Might Have Shifted Four Planets’ Paths, Study Finds
A mysterious interstellar object, estimated to be eight times the mass of Jupiter, may have significantly altered the orbits of Jupiter, Saturn, Uranus, and Neptune billions of years ago. A study suggests that this body passed remarkably close to the Sun, potentially influencing planetary trajectories. Simulations conducted by researchers indicate ...

Asteroid 2024 PT5 Linked to Lunar Surface, Reveals Planetary Defense Insights
Asteroid 2024 PT5, sized like a school bus, passed Earth in January at 1.1 million miles. Research suggests it originated from the moon, ejected thousands of years ago by an impact. Spectral analysis matched it to Apollo 14 lunar rocks, ruling out artificial origins. This is the second known lunar asteroid after 469219 Kamo’oalewa. The study hint...

Trillions of Comets Found in 74 Alien Star Systems, Unveiling Exocomets and Planetary Belts
A discovery of trillions of comets in 74 star systems has opened new doors for understanding the role of exocomets in planetary water sources. The planetesimal belts, detected using ALMA and SMA telescopes, offer crucial insights into the evolution of planetary systems and the potential for life-supporting water on distant planets. This research pa...

Seismic Data from NASA’s InSight Might Solve the Mystery of Mars’ Dichotomy
NASA’s InSight mission has provided seismic data shedding light on the Martian dichotomy, the split between Mars’ northern lowlands and southern highlands. Findings from the mantle’s seismic wave analysis suggest the split stems from ancient tectonic activity and magma dynamics, rather than asteroid impacts. Variations in crust thickness and ...

New Research Sheds Light on Iron’s Role in Earth’s Core Dynamics
Cutting-edge research using ultrafast X-ray absorption spectroscopy has revealed the structural and thermal behaviour of iron under extreme conditions mimicking Earth’s core. Findings show a hexagonal close-packed (hcp) structure at 240 GPa and 5,345 K, challenging prior theories favouring a body-centred cubic (bcc) form. The study provides criti...

Earth's Hidden 'Ignorosphere' Could Provide Insights into Auroras
A new dataset developed by Japanese researchers from the University of Tokyo provides valuable insights into Earth's upper atmosphere, specifically the mesosphere. Spanning 19 years, the data sheds light on phenomena like auroras, gravity waves, and their connection to space weather. The study, published in Progress in Earth and Planetary Science, ...

Interstellar Object Could Have Shifted Trajectories of Four Planets, New Research Shows
A recent study suggests that an interstellar object, possibly as massive as eight times Jupiter, may have passed through the solar system billions of years ago, significantly altering the orbits of its outer planets—Jupiter, Saturn, Uranus, and Neptune. Using computer simulations, researchers found that in about 1% of the scenarios, such a close ...

Mars Satellite Images Reveal Giant 'Kidney Beans,' Sparking Hints of Water and Life
NASA's Mars Reconnaissance Orbiter captured images of frozen sand dunes in Mars' northern hemisphere, revealing unique formations halted by carbon dioxide frost during winter. Unlike Earth's desert dunes, which shift with wind, these Martian dunes remain stationary until spring thaw releases their icy grip. Scientists study these features to unders...

Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere
Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

Amateur Astronomer Discovers Unexpected Composition of Jupiter’s Clouds
Recent observations by an amateur astronomer reveal that Jupiter’s clouds may not consist of ammonia ice as previously assumed. Using a technique called band-depth analysis, Steve Hill mapped ammonia concentrations in the planet’s atmosphere, finding reflective layers deeper than expected. These findings suggest the clouds may be composed of am...
