NASA's Jet Propulsion Laboratory News and Features 27 Aug 2019, 19:08 UTC NASA launched its Spitzer Space Telescope into orbit around the Sun on Aug. 25, 2003. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light.
McDonald Observatory 27 Aug 2019, 15:05 UTC Astronomers at The University of Texas at Austin’s McDonald Observatory, along with colleagues at Caltech and elsewhere, have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid belt to out beyond Neptune. Other giant planets with highly elliptical orbits have been found around other stars, but none of those worlds were located at the very outer reaches of their star systems like this one.
NASA's Goddard Space Flight Center 23 Aug 2019, 12:10 UTC This atmospheric image taken with the NASA/ESA Hubble Space Telescope shows a dark, gloomy scene in the constellation of Gemini (the Twins). The subject of this image confused astronomers when it was first studied — rather than being classified as a single object, it was instead recorded as two objects, owing to its symmetrical lobed structure (known as NGC 2371 and NGC 2372, though sometimes referred to together as NGC 2371/2).
NASA's Jet Propulsion Laboratory News and Features 22 Aug 2019, 16:48 UTC Thirty years ago, on Aug. 25, 1989, NASA's Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system's eighth planet. Marking the end of the Voyager mission's Grand Tour of the solar system's four giant planets - Jupiter, Saturn, Uranus and Neptune - that first was also a last: No other spacecraft has visited Neptune since.
NASA's Goddard Space Flight Center 21 Aug 2019, 12:51 UTC When it comes to making new stars, the party is almost over in the present-day universe. In fact, it’s been nearly over for billions of years. Our Milky Way continues to form the equivalent of one Sun every year. But in the past, that rate was up to 100 times greater. So if we really want to understand how stars like our Sun formed in the universe, we need to look billions of years into the past.
ESA Top News 21 Aug 2019, 09:09 UTC While the surface of the Moon has been well-documented with cameras on board several satellite missions, relatively little is known about the presence and nature of subsurface cavities. In volcanic areas of the lunar maria, planetary geologists have identified pits that could be related to the collapse of cavities such as lava tubes – where lava once flowed under the lunar surface.
MIT 20 Aug 2019, 04:00 UTC Nearly all of the oxygen in our universe is forged in the bellies of massive stars like our sun. As these stars contract and burn, they set off thermonuclear reactions within their cores, where nuclei of carbon and helium can collide and fuse in a rare though essential nuclear reaction that generates much of the oxygen in the universe.
