Nov 8th, 2025 - Launched by NASA in 2009, the Kepler space telescope was outfitted with equipment to discover and study Earth-sized planets in the Milky Way galaxy. It was named after the 17th century scientist and astronomer Johannes Kepler, renowned for his laws of planetary motion. It was a fitting name that served the telescope, its equipment, and its mission well. But while we heard a lot concerning the telescope's discoveries around that time, things have since gone quiet. Whatever happened to NASA's ... [Read More]

Nov 8th, 2025 - Follow Earth on Google While some black holes graze lightly, others devour their meals. In 2018, sky surveys picked up an outburst that brightened by a factor of 40 within a few months and, at its peak, shone with the light of about ten trillion suns. The flare now stands as the most powerful and most distant black hole flare ever recorded. The culprit sits ten billion light-years away in a galaxy whose core hosts an active galactic nucleus (AGN) called J2245+3743. Its central black hole is a ... [Read More]

Nov 8th, 2025 - Mere months after its long-awaited debut, the Vera C. Rubin Observatory is beginning to deliver on its promise to rewrite cosmic history. The observatory's colossal camera — perched atop a mountain in Chile — has yet to begin its official scientific survey. But just by perusing its first test image , astronomers have uncovered a surprise: a trail of light — called a stellar stream — extending from a well-known galaxy, suggesting that the galaxy once tore apart a much ...

Nov 7th, 2025 - Sky This Week is brought to you in part by Celestron. Friday, November 7 With a bright Moon still in the sky, we're a bit limited in what we can observe. But Hercules is home to a bright globular cluster visible during the evening hours: 6th-magnitude M13. Slowly setting in the west after dark, you have a few hours to catch this cluster before it gets too low. By 6 P.M. local time, M13 is still nearly 40° high in the west, located along one edge of the Keystone of Hercules between the stars ... [Read More]

Nov 7th, 2025 - Follow Earth on Google A NASA satellite has helped scientists trace the main power source of a weird, switching pulsar named J1023 to a fast, particle packed wind smashing into nearby gas. The crucial clue is that X-ray light and optical light line up in the same polarization angle, pointing to a single engine behind both. The full name of this object is PSR J1023+0038, a so-called transitional millisecond pulsar that flips between radio quiet and radio loud behavior. The most important number ... [Read More]

Nov 7th, 2025 - So it's confession time: I've been lying to you. I've said on many occasions that our Milky Way galaxy has a flat disk (like in this column or this one ). But it's not really flat—not even for a reasonable definition of the term. Now, in my defense, I wasn't lying per se; I was simplifying . That's a perfectly acceptable and even advantageous thing to do in science. When you have some complex thing that you're trying to understand or explain, it helps to make it as simple as possible so ... [Read More]

Nov 7th, 2025 - Nov. 7 (UPI) -- Saturn's Enceladus moon might be capable of supporting life, according to data collected by NASA's Cassini mission and compiled in a new study in the Science Advances journal. The moon is one of the most promising for supporting extra-terrestrial life among Saturn's 274 moons, and data show it is capable of long-term stability that would enable life to develop, the University of Oxford announced Friday. Researchers from Oxford, the Southwest Research Institute and the Planetary ... [Read More]

Nov 6th, 2025 - Follow Earth on Google Based on a new astrophysics model, scientists are making a bold claim. A handful of extremely massive stars, each more than 1,000 times the mass of the Sun, may have shaped the chemistry of the universe's oldest star clusters. These colossal stars could explain the unusual elemental patterns astronomers see in ancient stellar systems. The team's framework connects how these clusters formed to the unusual mix of elements we measure in their surviving stars, a link ... [Read More]

Nov 6th, 2025 - Reading time 4 minutes After the Big Bang, our universe began to expand at an exponential rate, an acceleration scientists have long attributed to a mysterious force known as dark energy. This idea—which earned its discoverers the Nobel Prize in 2011—has largely defined our understanding of cosmic growth for decades.  But new research is starting to challenge this long-held assumption. A team of researchers has uncovered new evidence suggesting that the universe may already be ... [Read More]

Nov 6th, 2025 - For decades, scientists believed that gold and other heavy elements were born from the cataclysmic collision of neutron stars. These rare events, observed across the cosmos, seemed to provide the intense conditions required to forge such elements. However, and the European Space Agency suggest that another, far more frequent process might have played an even greater role. Evidence drawn from two decades of space observations points to highly magnetised neutron stars, known as magnetars, as a ... [Read More]

Nov 6th, 2025 - Follow Earth on Google Astronomers piece together the story of our expanding universe, and whether or not that expansion is accelerating, by studying how bright certain stellar explosions look from Earth – Type Ia supernovae. These massive cosmic eruptions are a great measurement tool because all reach nearly the same peak brightness and follow predictable patterns as they flare up and fade away. By analyzing each supernova's color and light curve, scientists can adjust for those details ... [Read More]

Nov 5th, 2025 - The moon is still an extremely interesting place to study. The structure of the moon has perplexed astronomers for centuries before the advent of spacecraft. In the early 20th century, scientists were debating whether the moon was just a rocky object similar to Martian moons, or whether it had a more complex inner geology. Now, the debate has finally been settled. According to the latest mathematical models, the moon has a fluid outer core and a solid inner core, similar to Earth's. The inner ... [Read More]
