This still image was taken from a new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths – invisible to the naked eye – that the telescope can...
Telescopes help distant objects appear bigger, but this is only one of their advantages. Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible. read more
A study in the U.K. reaffirms a view of our galaxy held in the 1950s that was later challenged by images from the Spitzer Space Telescope.
You can't see it with any ordinary telescope, but without the Earth's magnetosphere—the magnetic field that encases the planet, blanketing it against gusts of deadly solar radiation—life here would have been all but impossible. Yet for as vital as it is to our survival, we understand very little about the magnetosphere. Show More Summary
The NASA/ESA Hubble Space Telescope has observed the variable star RS Puppis over a period of five weeks, showing the star growing brighter and dimmer as it pulsates. These pulsations have created a stunning example of a phenomenon known...Show More Summary
This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. Hubble took a series of photos of light flashes rippling across the nebula in a phenomenon known as a "light echo."
A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms. The new research, which is published...Show More Summary
Astronomers Without Borders (AWB) is a nonprofit organization aimed at knocking down national and cultural boundaries by encouraging a common interest in astronomy. Along with their message that we all share one sky, AWB is now selling a neat little grab-n-go telescope called OneSky. Show More Summary
Close binary stars cannot be resolved with today's optical telescopes, despite adaptive optics that removes the fuzziness caused by atmospheric turbulence. An international team of astronomers has built and mounted on a 3-meter California...Show More Summary
You know you scored a hotel room with a killer view if you walk in to find a telescope at the window. For many hotel guests, scoring such an amenity is pure luck; however, for travelers who know what they want (and it's an in-room telescope), there are a few properties that make such an offering part of the experience. Three hotels with in-room telescopes:
A new instrument that combines two high-resolution telescope techniques – adaptive optics and interferometry – has for the first time distinguished and studied the individual stars in a nearby binary star system, demonstrating promise for eventually picking out planets around other stars. read more
This NASA/ESA Hubble Space Telescope image shows the planetary nebula NGC 2452, located in the southern constellation of Puppis. The blue haze across the frame is what remains of a star like our Sun after it has depleted all its...
The Crab Nebula never fails to disappoint—and that's particularly true in this image, a view by the Herschel Space Observatory and the Hubble Space Telescope of the swirling cloud of dust and gas. Read more...
Using the new, high-frequency capabilities of the National Science Foundation’s Robert C. Byrd Green Bank Telescope (GBT), astronomers have captured never-before-seen details of the nearby starburst galaxy M82. These new data highlight...Show More Summary
Our vision is but limited. There are many beings living beyond our ken. Microscopes and telescopes increase the power of our vision; here...
A wide-field image of Pickering's Triangle taken with the National Science Foundation's Mayall 4-meter telescope at Kitt Peak National Observatory.
NASA’s Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface.Previous scientific findings from other sources already point to the existence of an ocean located under Europa's icy crust. Show More Summary
The scientists at the Antarctica South Pole Telescope have observed twisting patterns in the polarization of the cosmic microwave background—light that last interacted with matter very early in the history of the universe, less than 400,000 years after the Big...
South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation. read more
Awesome composite view from the Herschel Space Observatory and the Hubble Space Telescope. Here's the skinny: Read more...
