Circumbinary planets orbit two stars instead of one, moving around both in a wide path. These rare worlds experience complex day-night cycles and shifting sunrises. NASA’s Kepler-16b was the first confirmed example — a real-life version of a Tatooine-like planet from StarWars.

Did you know? Pi Day isn’t just for math lovers it’s celebrated in space too! NASA uses π (3.14159…) to calculate orbits, land rovers on Mars, and even explore distant exoplanets. So, while you enjoy your pie on Earth, remember that π helps us reach the stars! Happy Pi Day!

Did you know? Fast Radio Bursts are like cosmic prank calls—short, powerful flashes of radio waves from deep space. They last milliseconds, yet release more energy than the Sun does in days. The weird part? We still don’t know exactly what’s causing them!

Intuitive Machines’ Athena moon lander is now lounging on its side near the lunar south pole, legs pointing skyward like it’s stargazing. Despite the tumble, it kept transmitting data until Feb. 29, before going silent in the lunar night.

Did you know that the Milky Way is blowing enormous bubbles of gamma rays? These Fermi Bubbles, stretching 50,000 light-years above and below the galactic center, are believed to be the remnants of a powerful eruption from our galaxy’s supermassive black hole, Sagittarius A*.

Did you know that some supermassive black holes can be billions of times more massive than the Sun? These cosmic giants lurk at the centers of galaxies, shaping their evolution and sometimes launching powerful jets of energy that stretch for thousands of light-years. GIF by NBC NEWS

Did you know? While the Sun influences Earth’s climate, the current rise in global temperatures is driven by human activity, not solar variations. Studies show that solar output has remained stable, while greenhouse gas emissions continue to heat the planet at an unprecedented rate.

Did u know that if u fell into a black hole, time would slow down so much that, to an outside observer, u would appear frozen at the event horizon forever? But for u, the universe would speed up, and u might see its entire future unfold in moments before being crushed by gravity!

Did you know the Cat’s Eye Nebula (NGC 6543) is one of the most complex planetary nebulae ever discovered? Its intricate, layered structure suggests multiple episodes of mass ejection from its dying star.

The “Blaze Star” T Coronae Borealis is set to erupt in March 2025, brightening from magnitude +10 to +2. This rare nova, visible to the naked eye, happens once every 80 years don’t miss it!

Did you know that Sundays aren’t just for relaxing on Earth? On the Sun, every “Sunday” is a violent storm of solar flares and plasma eruptions! While we enjoy our day off, the Sun keeps burning, fusing 600 million tons of hydrogen into helium every second!

Astronomers have detected an unusual excess of gold and platinum in pulsars, hinting that dark matter might be playing a role in their formation. If confirmed, this discovery could reshape our understanding of both dark matter and heavy element creation in the universe!

NASA’s James Webb Space Telescope, humanity’s most powerful eye on the cosmos, faces a staggering 20% budget cut! With funding slashed, could this jeopardize groundbreaking discoveries about distant galaxies, exoplanets, and the origins of the universe?

Astronomers have peered into the past using the Gemini South telescope, uncovering a cosmic time capsule in the Small Magellanic Cloud! This tiny neighboring galaxy mirrors conditions from the early universe, offering a rare glimpse into how galaxies formed just a billion years after the Big Bang.

Astronomers using the Einstein Probe have discovered an unusual pair of “vampire” stars - one feeding off the other in a way that defies current models. This strange system challenges our understanding of stellar evolution.

NASA has discovered that antibiotic-resistant bacteria are thriving on the International Space Station, mutating to survive the harsh environment. Scientists fear these superbugs could pose serious health risks to astronauts on long-duration missions.

NASA warns that asteroid 2024 YR4 now has a 3.1% chance of striking Earth on December 22, 2032. This “city killer,” up to 300 feet wide, could cause massive destruction. Scientists are racing to track its path—will it be a near miss or a catastrophe?

Did you know that Earth’s gravity isn’t uniform everywhere? Due to variations in mass distribution, some regions experience slightly stronger or weaker gravity. For example, Canada’s Hudson Bay has lower gravity than expected, likely due to ice-age glacial melting and mantle convection.

We've just found asteroid 2024 YR4 which has a higher impact probability than any we've seen before, and the odds of it hitting Earth are increasing.
