TOI-4603b is nearly three times denser than Earth and orbits its star in just 7 days. Key Takeaways: TOI-4603b is a Jupiter-sized exoplanet with a staggering density of 14.1 g/cm³—greater than lead. With a mass of nearly 13 Jupiters, it’s on the edge between a giant planet and a brown dwarf. The planet’s highly oval…

NGC 1277, moving at 2 million mph, has barely changed since the early universe formed. Key Takeaways: Astronomers have identified NGC 1277 as a rare “relic galaxy” unchanged for 10 billion years. Unlike most galaxies, it has almost no blue globular clusters, indicating minimal outside influence. The galaxy is racing through space at 2 million…

A 2D universe could have stable gravity and complex networks, challenging traditional assumptions. Key Takeaways: A 2D universe with one time dimension might support life, defying past scientific assumptions. James Scargill’s study suggests a simpler gravitational field could allow stable orbits in 2D space. Neural networks in two dimensions may still develop the complexity required…

Sir Roger Penrose claims six ‘Hawking Points’ may be evidence of an earlier universe. Key Takeaways: Sir Roger Penrose believes remnants of a previous universe can still be seen today. He identified six ‘Hawking Points’—regions in the sky linked to ancient black holes. His theory suggests black holes from past universes evaporated, leaving behind detectable…

Webb and Hubble confirm the Universe’s expansion rate is accurate, but the mystery remains. Key Takeaways: Webb has verified that Hubble’s measurements of the Universe’s expansion rate were correct. The Hubble Tension, a major conflict between different expansion rate measurements, is still unresolved. Webb’s infrared data confirmed that Cepheid variable stars are reliable cosmic distance…

NASA has spent over $3 billion annually on SLS, but private rockets now cost 90% less. Key Takeaways  Boeing informed its workforce that NASA may cancel the SLS rocket program, leading to potential layoffs. Up to 400 employees could lose their jobs if contracts are not renewed. Originally set to launch in 2016, SLS debuted…

The Milky Way spans 100,000 light-years, yet after decades of searching, we’ve heard nothing. Key Takeaways Decades of searching for intelligent life have come up empty, suggesting extreme rarity. The absence of aliens gives humanity the freedom to explore and shape its destiny.  Even if aliens exist, immense distances make communication and contact nearly impossible….

The universe holds an estimated 40 quintillion stellar-mass black holes—about 1% of all normal matter. Key Takeaways: Scientists estimate 40 quintillion stellar-mass black holes exist in the universe, forming 1% of normal matter. This number was calculated by modeling the life cycles of stars, from formation to collapse. Black holes form when massive stars collapse,…

If the universe has existed forever, we can never prove it—science struggles with infinity. Key Takeaways: Scientists still don’t know whether the universe had a true beginning or has always existed. If the universe is infinite in time, it raises problems science may never be able to solve. The inflationary model explains early cosmic expansion,…

Astronomers traced a powerful radio burst 8 billion light-years away—one of the most distant ever found. Key Takeaways: Astronomers pinpointed the origin of a deep-space fast radio burst (FRB) nearly 8 billion light-years away. This is the second-ever non-repeating FRB to be traced back to its home galaxy. A Russian observatory also detected nine more…
