| September 3rd, 2026 08:41:39 EDT -0400 NASA scientists discover a giant 10-sided pattern on Saturn A huge 10-sided atmospheric pattern has appeared around Saturn’s south pole, giving the planet a surprising counterpart to its famous northern hexagon. Hubble data suggest the strange decagon only began emerging in the past few years and is still growing stronger. Researchers hope continued observations will reveal why it suddenly formed and whether it could persist for decades. |

The month ends with a glowing Harvest Moon rising near Saturn and faint Neptune. |
| September 3rd, 2026 03:48:14 EDT -0400 The universe has plenty of hydrogen. So why is star formation collapsing? Star formation across the universe has fallen dramatically over the past 4.5 billion years, but astronomers have uncovered a surprising twist: the supply of neutral hydrogen, a key ingredient for making stars, has barely declined. Using China’s FAST radio telescope and data from roughly 2.5 million galaxies observed by DESI, researchers found that star formation was about 2.5 times higher 4.5 billion years ago, while neutral hydrogen levels were only about 1.4 times higher. |

Seismic measurements suggest molten rock repeatedly evolved and recycled itself through the Martian crust, potentially across hundreds or thousands of kilometers. The discovery challenges long-held ideas about how complex planetary crusts form. |
| September 2nd, 2026 00:25:48 EDT -0400 Earth may have lost the Sun’s protective shield millions of years ago NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares of its youth. Those events may help explain ancient ice ages as well as how early Earth stayed warm enough for liquid water when the Sun was much dimmer. |
| September 1st, 2026 01:33:37 EDT -0400 NASA delays Crew-13 launch after leak found on SpaceX Dragon NASA and SpaceX have delayed Crew-13 after finding an oxidizer leak in the Dragon spacecraft’s propulsion system during prelaunch preparations. Engineers are investigating the problem before the four-person crew can begin its journey to the International Space Station. |
| September 1st, 2026 01:43:54 EDT -0400 NASA’s Swift telescope is back, but time is running out NASA has brought two of Swift’s telescopes back online after technical problems derailed a commercial mission intended to rescue the aging observatory by raising its orbit. With atmospheric drag pulling the spacecraft downward faster than expected, scientists may have only another month or two before Swift falls below a critical operating altitude. |
| September 4th, 2026 06:07:20 EDT -0400 Dying radio galaxies fade faster than scientists expected Astronomers have identified a surprisingly young population of fading radio galaxies whose supermassive black holes have already switched off their powerful jets. The confirmed remnants range from about 8 to 42 million years old, suggesting many may disappear from view much faster than previously recognized. More distant remnants also seem to fade especially quickly, helping explain why they have been so difficult to detect. |
| August 31st, 2026 05:23:21 EDT -0400 NASA’s Roman Space Telescope launches to reveal the Universe’s darkest secrets NASA’s Roman Space Telescope has launched on a million mile journey to L2, where it will scan huge portions of the cosmos for clues about dark matter, dark energy, and distant worlds. With survey speeds roughly 1,000 times faster than Hubble and a torrent of 1.4 terabytes of data per day, Roman could uncover cosmic surprises astronomers have never seen before. |
| September 2nd, 2026 10:51:21 EDT -0400 Interstellar solar sails hit a strange problem at 75% of light speed Solar sails pushed by powerful lasers could reach incredible speeds, but relativity may eventually make the light itself work against them. At around 75% of the speed of light, scattered photons can begin creating drag, adding a surprising obstacle to interstellar travel. |
| August 30th, 2026 11:05:09 EDT -0400 This strange “spacetime crystal” can suddenly become a black hole Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving researchers a new tool for studying primordial and microscopic black holes. |
| August 31st, 2026 01:00:01 EDT -0400 Rocky planets may have formed just 100 million years after the Big Bang Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young star to suggest that Earth-like worlds could have appeared far earlier than previously believed. |
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.
