| June 6th, 2026 09:24:27 EDT -0400 Tiny X-ray telescope could unlock the Moon's hidden chemistry A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon. Researchers used detailed mission simulations to show that a compact telescope orbiting the Moon could identify key elements across the entire lunar surface, helping reveal how the Moon formed and evolved. |
| June 5th, 2026 08:32:00 EDT -0400 Hidden supermassive black hole pairs may finally have a visible signal Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity. The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision. |
| June 6th, 2026 00:24:47 EDT -0400 NASA just proved spacecraft can switch between multiple satellite networks NASA’s PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems. The mission is now expanding to test new capabilities that could help create a more flexible, reliable communications infrastructure for future space missions. |
| June 5th, 2026 08:18:21 EDT -0400 Magnetic fields may be the secret behind binary star formation Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer simulations show that magnetic fields surrounding newborn stars can act like a cosmic brake, stripping away angular momentum and allowing two still-forming protostars to spiral closer together instead of drifting apart. |
| June 4th, 2026 01:17:24 EDT -0400 NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system. Scientists believe the methane was hidden beneath the surface and only emerged after solar heating reached deeper icy layers. |
| June 3rd, 2026 11:54:24 EDT -0400 Venus will disappear behind the Moon in a rare June sky event June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus for viewers in parts of the Americas. The month also marks the start of astronomical summer and the return of spectacular deep-sky targets like the Ring Nebula and Veil Nebula. |
| June 2nd, 2026 07:08:18 EDT -0400 A stellar “Rosetta stone” reveals the source of mysterious cosmic signals Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours. |
| June 1st, 2026 02:53:34 EDT -0400 NASA’s Roman telescope could reveal 100,000 hidden worlds NASA’s Roman Space Telescope could revolutionize the search for alien worlds by discovering around 100,000 exoplanets—far more than all previous missions combined. It will look deep into unexplored parts of the Milky Way, helping scientists compare planetary systems across very different galactic environments. The mission will also uncover rare Earth-sized planets, study thousands of exotic alien atmospheres, and provide a treasure trove of data that could reshape our understanding of how planets form. |
| June 1st, 2026 07:38:16 EDT -0400 Hubble captures M88 on a perilous journey that could change it forever A stunning spiral galaxy called Messier 88 is racing through the crowded Virgo Cluster on a journey that will dramatically reshape its future. At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful spiral arms sparkle with young star clusters and dark clouds of dust. But as M88 plunges deeper into the cluster over the next few hundred million years, powerful forces will strip away much of the gas it needs to create new stars. |
| May 29th, 2026 04:36:58 EDT -0400 Astronomers finally solve Saturn’s decades-long spin mystery A decades-old mystery about Saturn has finally been solved thanks to the James Webb Space Telescope. Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s unprecedented observations revealed that Saturn’s northern lights actively heat the atmosphere, creating winds that generate electrical currents, which then power the aurora all over again in a self-sustaining cycle. |
| May 29th, 2026 02:05:08 EDT -0400 Rogue planet moons could harbor alien life for billions of years Scientists say moons around rogue planets wandering through the galaxy could remain warm enough for life thanks to tidal heating and hydrogen-rich atmospheres. These dark, starless worlds may have had stable oceans for billions of years — long enough for complex life to potentially emerge. |
| May 27th, 2026 06:24:22 EDT -0400 NASA’s Webb telescope discovers a planet where rock clouds vanish every night A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like 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.
