Hubble’s Newest View of Jupiter Shows New Storms Brewing

News from NASA: This latest image of Jupiter, taken by NASA’s Hubble Space Telescope on August 25, 2020, was captured when the planet was 406 million miles from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of…

Phosphine Discovery in Venus’ Atmosphere Raises the Big Question of Life

Today an international team of scientists led by Jane Greaves of Cardiff University in the UK announced the discovery of phosphine (PH3) in the atmosphere of our neighboring planet Venus — a detection made using data from ground-based telescopes located in Hawaii and Chile. On Earth, phosphine is created for industrial uses in labs and by…

Betelgeuse’s Recent Dimming Likely Caused by a Dusty Outburst

From October 2019 to February 2020, Betelgeuse (the bright orange star at Orion’s right shoulder, not Tim Burton’s magical necroprankster) was seen to dim dramatically, even more so than it typically does. It was something that wasn’t just observed with telescopes but also it was quite obvious to the naked eye from most locations. This…

Ceres’ Salty Mound is the Result of Ongoing Geologic Activity

First observed with the Hubble Space Telescope in 2003, the curious bright spots on the dwarf planet Ceres—the largest world in the main asteroid belt between Mars and Jupiter—was brought into exquisite focus with the arrival of NASA’s Dawn spacecraft in 2015. The largest and brightest of these spots—a single 340-meter-high mound named Cerealia Facula…

What’s the Weather on Jupiter? Cloudy with a Chance of Mushballs

Recent findings from NASA’s Juno mission, in orbit around Jupiter since July 4, 2016, may have solved an ongoing mystery about the composition of the giant planet’s upper atmosphere; namely, the case of the missing ammonia. (Jupiter is composed mostly of hydrogen and helium but also contains trace amounts of ammonia, methane, and water vapor.) North…

NASA’s Perseverance Rover Launches to Mars

Today, July 30, 2020 at 7:50 a.m. EDT (11:50 UTC) NASA’s Mars 2020 rover Perseverance launched from Cape Canaveral, Florida aboard a ULA Atlas V 541 rocket. The weather at the Cape was picture-perfect and the launch went smoothly, sending NASA’s newest robotic mission to Mars on its way for an anticipated arrival and landing…

Ganymede’s Polar Ice is ‘Disrupted’ by Jupiter’s Plasma

The first-ever infrared images of Ganymede’s north pole, taken on December 26, 2019 with the JIRAM instrument aboard NASA’s Juno spacecraft, show that the gigantic moon’s polar ice lacks any crystalline structure like the water ice we’re familiar with typically does here on Earth. This is a result of constant bombardment by charged plasma in…

For the Umpteenth Time No NASA Didn’t Change the Zodiac

Come on everyone, no. Just…no. NASA did not “change your star sign.” NASA neither creates “star signs” nor names or changes them. This is because 1. that’s not NASA’s job, and 2. “star signs”—i.e., astrology—is junk science. (And that’s being grossly generous with the term “science.”)

Solar Orbiter’s First Images Reveal the Sun Covered With Tiny “Campfires”

The pictures are in! The first image data from the cameras aboard ESA’s Solar Orbiter were revealed today, July 16 2020, and reveal many features on our Sun we’ve never been able to see before—including small-scale flare activity dubbed “campfires.” (I say small-scale but they’re actually the size of entire countries!) “The Sun might look…

How To Spot Comet NEOWISE

Info from NASA on July 14, 2020: Observers in the Northern Hemisphere are hoping to catch a glimpse of Comet C/2020 F3 (NEOWISE) as it zips through the inner solar system before it speeds away into the depths of space. [Editor’s note: many already have!] Discovered on March 27, 2020 by NASA’s Near-Earth Object Wide-field…
