September 3rd, 2025 10:10:15 EDT -0400 The Sun’s hidden particle engines finally exposed Solar Orbiter has identified the Sun’s dual “engines” for superfast electrons: explosive flares and sweeping coronal mass ejections. By catching over 300 events close to their origin, the mission has solved key mysteries about how these particles travel and why they sometimes appear late. The findings will improve space weather forecasts and help shield spacecraft and astronauts from solar radiation. |
September 3rd, 2025 10:01:31 EDT -0400 A weirdly shaped telescope could finally find Earth 2. 0 Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding star. This approach could uncover dozens of nearby worlds that might host life. |
September 4th, 2025 11:02:24 EDT -0400 A monster molecular cloud has been discovered in our galaxy – “No one had any idea this existed” Researchers spotted a colossal cloud of gas and dust in the Milky Way, filled with turbulent motion, newborn star seeds, and even a natural microwave laser. This newly found Midpoint cloud appears to funnel material toward the galactic center, offering key insights into star formation in extreme cosmic regions. |
September 2nd, 2025 22:56:49 EDT -0400 Warped planet nurseries rewrite the rules of how worlds are born Astronomers using ALMA have discovered that planet-forming discs are not flat and serene but subtly warped, reshaping our understanding of how planets form. These slight tilts, similar to those seen among planets in our Solar System, suggest that planetary systems emerge in more chaotic and dynamic conditions than once believed. The findings point to new connections between disc warps, gas flow, turbulence, and the feeding of young stars, raising exciting questions about the forces shaping worlds across the cosmos. |
September 2nd, 2025 10:25:58 EDT -0400 Distant suns covered in dark spots could shape the search for life A new model called StarryStarryProcess lets scientists map star spots with precision, improving how exoplanets are studied. By factoring in both transits and stellar rotation, it provides richer details about stars and their influence on planetary signals. |
September 2nd, 2025 10:03:12 EDT -0400 NASA’s SPHEREx Captures Comet 3I/ATLAS, a Visitor From Beyond the Solar System NASA’s SPHEREx joined Webb and Hubble in studying interstellar comet 3I/ATLAS, gathering data on its size, chemistry, and physical traits. While harmless to Earth, the comet provides scientists a rare opportunity to learn more about solar system wanderers. |
September 2nd, 2025 08:49:55 EDT -0400 NASA’s Webb Space Telescope Reveals Secrets of Interstellar Comet 3I/ATLAS Webb, Hubble, and SPHEREx are joining forces to study the interstellar comet 3I/ATLAS, revealing details about its structure and chemistry. The comet isn’t dangerous, but it’s offering scientists a rare chance to explore material from outside our solar system. |
August 31st, 2025 23:01:40 EDT -0400 Scientists stunned by the Universe’s first known black hole Just 500 million years after the Big Bang, a colossal black hole, 300 million times the mass of the Sun, was already blazing at the heart of a tiny, brilliant galaxy. Found with JWST, this discovery could explain the strange "Little Red Dots" seen in the early cosmos and rewrites what we thought was possible for black hole growth. |
August 31st, 2025 20:05:10 EDT -0400 NASA’s x-ray telescope finds bizarre features in a cosmic hand Astronomers have taken a fresh look at the famous “Hand of God” pulsar, combining X-ray data from NASA’s Chandra Observatory with new radio observations from the Australia Telescope Compact Array. At the center is pulsar B1509-58, a rapidly spinning neutron star only about 12 miles wide that powers a nebula stretching 150 light-years across. The strange hand-shaped structure continues to surprise researchers, revealing puzzling filaments, patchy remnants, and boundaries that defy expectations. |
September 1st, 2025 04:09:12 EDT -0400 Dark matter could be turning giant planets into black holes Astronomers have found over 5,000 exoplanets, and now scientists think these distant worlds could unlock one of the universe’s greatest mysteries: dark matter. A new study suggests that Jupiter-like planets may gradually collect superheavy dark matter particles in their cores, which could one day collapse into planet-sized black holes. |
September 1st, 2025 04:36:40 EDT -0400 NASA finds Titan’s alien lakes may be creating primitive cells Saturn’s moon Titan may be more alive with possibilities than we thought. New NASA research suggests that in Titan’s freezing methane and ethane lakes, simple molecules could naturally arrange themselves into vesicles—tiny bubble-like structures that mimic the first steps toward life. These compartments, born from splashing droplets and complex chemistry in Titan’s atmosphere, could act like primitive cell walls. |
August 31st, 2025 00:59:18 EDT -0400 NASA’s Webb Telescope just found 300 galaxies that defy explanation Astronomers at the University of Missouri, using the James Webb Space Telescope, have uncovered 300 unusually bright cosmic objects that may be some of the earliest galaxies ever formed. By applying techniques like infrared imaging, dropout analysis, and spectral energy distribution fitting, the team has identified candidates that could force scientists to rethink how galaxies emerged after the Big Bang. |
Jan 2013 - Two comets to get excited about. One is Comet PANSTARRS,
which will be brightest in March 2013. The other is Comet ISON, which might
become a daylight comet in late 2013. Although a comets movement in our sky
can be predicted, its brightness cannot be. Its too early to know whether
Comet PANSTARRS or Comet ISON the two exciting comets of 2013 will dazzle
or fizzle.
Comet PANSTARRS
By October 2012, its surrounding coma was seen to be large and fine at an estimated 75,000 miles (120,000 kilometers) wide. In March 2013, by some estimates, this comet should get as bright as Venus,
Comet ISON
Last year, Russian astronomers Vitaly Nevsky and Artyom Novichonok discovered a new gigantic comet that is currently approaching Earth. The ISON comet, which is expected to become brighter than the full moon, will be visible to the naked eye by late 2013.
Comet ISON has only been visible through powerful telescopes. In November 2013, heat from the sun will vaporize ices in the comet's body, creating what could be a spectacular tail that will be visible in Earth's night sky without telescopes or even binoculars from about October 2013 through January 2014.
Comet ISON will come within 800,000 miles (1.2 million km) of our suns surface on November 28. Thats over 100 times closer to the sun than Earth. This close pass to the sun might cause Comet ISON to break to pieces. January 2014 may see a meteor shower produced by streams of debris from the ISON comet.
