When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous — so much so that it forms what looks like an especially bright new star that slowly fades away over time.

After nearly 16 years of exploring the cosmos in infrared light, NASA's Spitzer Space Telescope will be switched off permanently on Jan. 30, 2020. By then, the spacecraft will have operated for more than 11 years beyond its prime mission, thanks to the Spitzer engineering team's ability to address unique challenges as the telescope slips farther and farther from Earth.

It’s no secret that sending the first astronauts to Mars will be a monumental challenge marked with many “firsts.” Given that NASA hasn’t launched a manned mission beyond low-Earth orbit in 47 years – crews will need a guide to show them the way. Enter the next rover the U.S. space agency plans to send to the Red Planet.

This abstract night-sky photo shows the full moon peeking through wispy clouds and barren tree branches while surrounded by brilliant, blue lunar corona. A relatively rare sight, this optical phenomenon occurs when bright moonlight is diffracted by water droplets in thin clouds that drift in front of the lunar disk.

We’re getting first results from the Gemini Planet Imager Exoplanet Survey (GPIES), a four-year look at 531 young, nearby stars that relies on the instrument’s capabilities at direct imaging. Data from the first 300 stars have been published in The Astronomical Journal, representing the most sensitive, and certainly the largest direct imaging survey for giant planets yet attempted. The results of the statistical analysis are telling: They suggest that planets slightly more massive than Jupiter in outer orbits around stars the size of the Sun are rare.

When InSight landed on Mars on Nov. 26th, 2018, it deployed a parachute to slow its descent through the thin Martian atmosphere. As it approached the surface, it fired its retro rocket to slow it even more, and then gently touched down on the surface. As it did so, its retro rockets excavated two small pits in the Martian soil.

In 1961, the Swedish astronomer Bengt Westerlund was taking photographic plates of the sky near or on the plane of the Milky Way — that is, looking deep into the murk of our flattened disk of a galaxy. He was observing at Mt. Stromlo in Australia, where the Milky Way rises high above the horizon, giving fantastic views of the galaxy. In the images he found something very interesting: A dense cluster of stars, heavily obscured by clouds of dust between us and it. Cold interstellar dust (located far away from and between stars in the galaxy) is made of tiny grains of rocky or carbonaceous material, and is excellent at absorbing light. It not only makes objects behind it look fainter, but it also reddens the light, in the same way the Sun looks redder when it’s near the horizon (astronomers call this extinction).

Saturn's rings are a complex mix of stripes, speckled textures and other odd features that appear to be sculpted by the planet's moons. So say researchers who have crunched the final data collected by NASA's Cassini spacecraft just before it plunged through the planet's rings to its demise in 2017. They've published their findings in the journal Science today, providing some of the most detailed insights ever obtained into the iconic rings.
