April 24th, 2025 12:17:01 EDT -0400 Scientists use James Webb Space Telescope to better understand solar system's origins
Using the James Webb Space Telescope (JWST), scientists analyzed far-away bodies -- known as Trans-Neptunian Objects (TNOs) -- and found varying traces of methanol. The discoveries are helping them better classify different TNOs and understand the complex chemical reactions in space that may relate to the formation of our solar system and the origin of life.
April 23rd, 2025 11:26:41 EDT -0400 Innovative approaches advance search for ice on the moon
Scientists and space explorers have been on the hunt to determine where and how much ice is present on the Moon. Water ice would be an important resource at a future lunar base, as it could be used to support humans or be broken down to hydrogen and oxygen, key components of rocket fuel. Researchers are now using two innovative approaches to advance the search for ice on the Moon.
April 22nd, 2025 13:13:30 EDT -0400 Astronomers discover a planet that's rapidly disintegrating, producing a comet-like tail
A planet 140 light-years from Earth is rapidly coming apart due to its close proximity to its star. The roasting planet is effectively evaporating away: It sheds an enormous amount of surface minerals as it whizzes around its star.
April 21st, 2025 16:31:03 EDT -0400 Did it rain or snow on ancient Mars? New study suggests it did
Geologists weigh in on a long-running debate about Mars: Billions of years ago, was the Red Planet warm and wet or cold and dry?
April 18th, 2025 23:55:14 EDT -0400 Turning down starlight to spot new exoplanets
Researchers have developed a new coronagraph that could make it possible to see distant exoplanets obscured by light from their parent stars.
April 18th, 2025 13:37:25 EDT -0400 Scientists probe the mystery of Titan's missing deltas
New research finds that despite large rivers and seas of liquid methane, Saturn's moon Titan seems mostly devoid of river deltas, raising new questions about the surface dynamics on this alien world.
April 17th, 2025 14:49:06 EDT -0400 Curiosity rover finds large carbon deposits on Mars
Research from NASA's Curiosity rover has found evidence of a carbon cycle on ancient Mars.
April 16th, 2025 20:40:34 EDT -0400 Strongest hints yet of biological activity outside the solar system
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.
April 16th, 2025 15:21:24 EDT -0400 Ever wonder why some meteor showers are so unpredictable?
Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.
April 16th, 2025 15:19:17 EDT -0400 'Big surprise': Astronomers find planet in perpendicular orbit around pair of stars
Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a stellar pair.
April 16th, 2025 13:57:50 EDT -0400 The most distant twin of the Milky Way ever observed
An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang and already shows a remarkably mature structure, with a central old bulge, a large star-forming disk, and well-defined spiral arms. The discovery was made using data from the James Webb Space Telescope (JWST) and offers important insights into how galaxies can form and evolve so rapidly in the early Universe.

Scientists have designed a 'cosmic radio' detector which could discover dark matter in 15 years.

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.
