Planetary Parade In February 2026: When And How To Watch Six Planets Align In A Rare Sky Spectacle
Light pollution won't significantly hinder viewing, but clouds can be problematic, so clear skies are essential.

Uranus and Neptune May Be Rock-Dominated Planets, Study Suggests
Uranus and Neptune may not be true ice giants after all. New research using advanced hybrid simulations suggests the distant planets could be dominated by rocky material rather than water-rich ices. The findings challenge decades of planetary models and may help explain the planets’ unusual, non-dipolar magnetic fields. Scientists say future dedi...

Uranus and Neptune May Be Rocky Worlds Not Ice Giants, New Research Shows
A new analysis challenges decades-old assumptions about Uranus and Neptune, revealing that both planets may contain far more rock than icy materials. These findings help explain their strange magnetic fields and show that traditional "ice giant" models may be incomplete. Scientists say only dedicated future missions can uncover the true interior ma...

Reflective Clouds And Metallicity, All About Exotic Atmosphere Of Rare "Ultra-Hot Neptune"
With temperatures reaching almost 2,000 degrees Celsius on its dayside, LTT 9779 is one of the few known planets in the "hot Neptune desert".

Astronomers Spot Possible Primordial Cluster Beyond Neptune
According to Princeton researchers, the classical belt's structure should be understood as consisting of three major components.

NASA's James Webb Space Telescope Telescope Challenges Old Theories on Mini-Neptune Worlds
New models suggest mini-Neptunes—planets smaller than Neptune with thick gas envelopes—may have solid rocky surfaces instead of molten magma. Data from NASA’s JWST revealed high-pressure atmospheres capable of compressing molten rock into solid crusts. This discovery challenges earlier assumptions and offers key insights into exoplanet compos...

Anthropic Tipped to Release Claude 4.5 Opus Soon, Said to Be Focused on Resisting Jailbreaks
Anthropic is reportedly preparing to launch Claude 4.5 Opus, the frontier version of its Claude 4.5 series. A leak suggests the company has shared a new Neptune V6 model with red-teamers for testing jailbreak resistance. The firm is said to be offering bonuses for finding universal jailbreaks, highlighting its ongoing focus on AI safety and robustn...

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.

Uranus and Neptune May Be More Rock Than Ice, New Research Suggests
A new pre-print study proposes that Uranus and Neptune might not be “ice giants” after all. Using assumption-free models, scientists found their interiors could range from mostly icy to mostly rocky, suggesting we know far less about these distant worlds and that new missions are essential to solve the mystery.

NASA Missions Uncover a Diverse Galaxy of Super-Earths, Raising New Questions About Planetary Evolution
Super-Earths are among the most common planets in the galaxy, yet none exist in our solar system. Larger than Earth but smaller than Neptune, they range from ocean-covered worlds to scorched, atmosphere-less rocks. Some orbit within habitable zones, making them prime candidates for life. NASA’s Kepler and TESS missions, along with upcoming telesc...
