Comet 2024 G3 (ATLAS) Becomes the 'Great Comet' of 2025 with Stunning Display
Comet 2024 G3 (ATLAS) has captured the attention of astronomers with its incredible brightness and distinct tail structure. First observed in 2024, it became the brightest comet in 18 years, and it even reached a rare feat of being visible during daylight. This comet, which passed closest to the sun in January 2025, has earned the title of "Great C...

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 ...

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...

200 Years On, 'Mystery Volcano' That Cooled Earth In 1831, Found
The annual average temperatures in the Northern Hemisphere came down by around 1 degree Celsius during one of the most powerful eruptions in the 19th century.

Solar Storm Sparks Northern Lights Across Western Hemisphere on New Year's Eve
Solar storms on New Year’s Eve sparked breathtaking auroras across the US and Europe, with vibrant displays visible as far south as California, Austria, and Germany. Two coronal mass ejections (CMEs) struck Earth’s magnetic field, causing geomagnetic storms that reached G3 levels on January 1.

Winter Solstice 2024: All About The Shortest Day And Longest Night Of The Year
Winter Solstice 2024: The Earth's tilt of approximately 23.5 degrees on its axis is the primary reason for the occurrence of the winter solstice and the changing seasons.

Irminger Sea’s Crucial Role in Atlantic Ocean Current Collapse Identified
A new study highlights the vital role of the Irminger Sea in the Atlantic Meridional Overturning Circulation (AMOC). Increasing meltwater from the Arctic is weakening this critical ocean current, which regulates global climate. The research suggests that disruptions in the Irminger Sea could cause widespread climate shifts, including cooling in the...

Rare Comet Tsuchinshan-ATLAS Appears in Earth Skies After 80,000 Years, Best Viewing Said to be This Week
The anticipated Comet Tsuchinshan-ATLAS (C/2023 A3) has been visible in the evening sky for Northern Hemisphere observers starting October 11. Discovered in early 2023, the comet reached its closest point to Earth on October 12, making it a prime time for observation. Spot it near Venus about 40 minutes after sunset. The best views are expected ove...

Aurora Season in September 2024 Could Bring Vibrant Northern Lights Due to Earth's Tilt
Auroras are expected to be more intense around September's equinox due to the Russell-McPherron Effect. The phenomenon occurs when Earth's magnetic field temporarily aligns with the solar wind, allowing charged particles to penetrate and interact with our atmosphere. This interaction causes vibrant Northern Lights, especially during the equinox. Wi...

The 2024 Perseid Meteor Shower To Peak Tonight: Where And How To Watch
The shower is expected to produce around 50-75 meteors per hour at its peak, with the possibility of fireballs and meteors with long trains.

Summer Solstice 2024: June 21 Will Be The First Day Of Summer. Here's Why
The summer solstice happens when the Earth's axial tilt is most inclined towards the Sun, resulting in the Sun reaching its highest position in the sky.
