NASA's Roman Space Telescope is about to reveal 100,000 previously unknown planets across our galaxy, helping scientists understand how worlds form in different cosmic neighborhoods. The mission will explore uncharted regions of the Milky Way, including Earth's birthplace near the galactic center.
When Danish astronomer Tycho Brahe spotted a "new star" in 1572, he didn't just witness a supernova—he sparked the scientific revolution that transformed how humanity understands the universe. As AI promises another scientific revolution, this cosmic explosion reminds us how far observation and measurement have brought us.
Astronomers discovered two pairs of Jupiter-sized planets floating through space without a star, strengthening evidence that these mysterious objects are real. The finding comes from a different region of the Milky Way than previous discoveries.
Astronomers just weighed a black hole from when the universe was only 700 million years old and discovered something remarkable: it's so massive it likely formed before its own galaxy. The finding could finally explain how the universe's first supermassive black holes came to be.
The James Webb Space Telescope just gave us the most detailed look ever at how star clusters emerge from cosmic clouds, tracking nearly 9,000 clusters at different life stages. The discovery reveals a surprising twist about where planets can form.
Scientists just discovered a planet where clouds made of rocky minerals appear every morning and vanish by nightfall. The James Webb Space Telescope gave astronomers their clearest view yet into this bizarre alien world.
Jupiter, Venus, and Mercury will create a stunning "planetary bridge" visible in the western sky on May 27, offering skywatchers a rare celestial show. You won't need fancy equipment to catch this mini parade of planets stretching between the constellations of Gemini and Taurus.
NASA's James Webb Space Telescope discovered a supermassive black hole that formed before its host galaxy, flipping our understanding of cosmic origins upside down. The 50-million-solar-mass black hole makes up two-thirds of its tiny galaxy's total mass.
Scientists discovered a giant planet where clouds made of minerals appear every morning and disappear by nightfall. The James Webb Space Telescope captured this wild daily weather cycle 700 light years from Earth.
NASA's James Webb Space Telescope discovered a supermassive black hole that existed just 700 million years after the Big Bang, challenging everything scientists thought they knew about how these cosmic giants form. The black hole makes up two-thirds of its entire system's mass, suggesting it formed first and the galaxy came later.
Millions of centuries-old manuscripts written on palm leaves are being rescued across India using traditional herbal oils and modern climate-controlled labs. These fragile texts contain poetry, medicine, and astronomy that would otherwise crumble into dust.
Harvard scientists used tiny quantum computers to solve a century-old problem blocking astronomers from building giant optical telescope networks. The breakthrough could one day help us photograph distant planets and stars with unprecedented clarity.
Scientists finally discovered what powers the brightest stellar explosions ever seen: ultra-magnetic newborn stars spinning hundreds of times per second. The breakthrough came after NASA's Fermi telescope detected gamma rays from a supernova 440 million light-years away.
A Chinese space telescope just detected a mysterious pattern hidden in cosmic rays from across the galaxy, solving a puzzle physicists have been chasing since 1912. The discovery could finally reveal how the universe's most energetic particles get their incredible power.
Scientists finally know why the universe's biggest stars seemed to vanish before exploding. A dust shroud so thick it fooled Hubble was hiding them all along.
Astronomers detected an unprecedented gamma-ray burst lasting seven hours—the longest ever recorded—and now believe it came from a black hole devouring a helium star. The discovery could help scientists spot similar cosmic events in the future.
New telescope images reveal that where a galaxy lived determined how it grew, even when the universe was barely a billion years old. The discovery shows cosmic "neighborhood effects" began far earlier than scientists thought possible.
Scientists have finally captured definitive gamma-ray evidence of a supercharged supernova, revealing how the most magnetic objects in the universe are born. After nearly 20 years of searching, NASA's Fermi spacecraft witnessed a stellar explosion powered by a newborn magnetar spinning 700 times per second.
A woman who hunts for space dust on rooftops and streets just got her own asteroid. The 1.5-kilometer rock orbiting between Mars and Jupiter now bears her name.
Scientists just mapped weather on a distant world for the first time, and it's nothing like Earth. A giant planet 700 light-years away has mornings filled with mineral clouds and crystal-clear nights, separated by a 170°C temperature swing.
