| June 11th, 2026 08:02:51 EDT -0400 NASA reveals Artemis III crew for one of the most complex space missions ever NASA has selected the Artemis III crew for a high-stakes 2027 mission designed to test the future of lunar exploration. Astronauts will launch aboard Orion and perform unprecedented docking operations with lunar landers being developed by both Blue Origin and SpaceX. The mission will require a remarkable sequence of heavy-lift rocket launches and complex in-space maneuvers, helping pave the way for future Moon landings and eventually crewed missions to Mars. |
| June 11th, 2026 07:47:04 EDT -0400 James Webb reveals two completely different twilights on an alien world JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b. Fierce winds appear to carry heat from the planet’s permanent dayside, making the evening side hotter and more expanded. Scientists also found signs that water is being broken apart by extreme temperatures and that mysterious mineral clouds may be shaping the cooler side’s atmosphere. |
| June 10th, 2026 07:24:15 EDT -0400 MIT’s new spacecraft engine could send tiny satellites to Mars MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do. The approach combines quick bursts of speed with highly efficient long-range propulsion in a single compact system. A NASA-supported CubeSat mission will soon test the technology in orbit. |
| June 9th, 2026 07:18:10 EDT -0400 Scientists think they solved the mystery of the Amaterasu particle The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space. This idea could help explain how these rare particles reach Earth and provide new clues about the powerful cosmic explosions that create them. |
| June 8th, 2026 21:52:02 EDT -0400 Planet nine mystery deepens as new discovery challenges hidden planet theory Astronomers have spent years searching for a possible hidden giant planet far beyond Neptune. Unusual orbits among distant Kuiper Belt objects have fueled the Planet Nine theory, but recent discoveries are challenging the idea by showing more stable motion than expected. If Planet Nine exists, it may be much farther away than originally thought. |
| June 8th, 2026 19:47:25 EDT -0400 NASA updates worsening ISS leak after crew safety alert NASA says a long-running air leak aboard the ISS recently worsened, leading engineers to investigate new suspected crack locations and consider a riskier repair strategy. Astronauts were temporarily moved into a safe haven as a precaution before the repair was postponed for further analysis. |
| 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. |
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 comet’s movement in our sky
can be predicted, its brightness cannot be. It’s 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 sun’s surface on November 28. That’s 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.
