A Solar Eclipse on Jupiter

NASA/JPL-Caltech/SwRI/MSSS/Kevin M. Gill A recent series of images released by NASA on September 12th, 2019, captured a solar eclipse on Jupiter as its moon, Io, casts a shadow on the colossal planet’s north equatorial belt. The raw images were then processed by NASA software engineer and data wrangler, Kevin M. Gill, in the gallery you see here. For those curious as to why the moon’s shadow on Earth during an eclipse appears fuzzy while Io’s shadow is so sharp, astrophysicist Dr. Katherine Mack explains: Io is so big & close…

The Aerosols of Earth

Image Credit: NASA/Joshua Stevens/Adam Voiland [NASA, Yvette Smith] Take a deep breath. Even if the air looks clear, it is nearly certain that you will inhale millions of solid particles and liquid droplets. These ubiquitous specks of matter are known as aerosols, and they can be found in the air over oceans, deserts, mountains, forests, ice and every ecosystem in between. If you have ever watched smoke billowing from a wildfire, ash erupting from a volcano or dust blowing in the wind, you have seen aerosols. Satellites like NASA’s Earth-observing…

Glacial melting in Antarctica may become irreversible

Thwaites glacier is likely to thaw and trigger 50cm sea level rise, US study suggests A Nasa-funded study found instability in the Thwaites glacier meant there would probably come a point when it was impossible to stop it flowing into the sea and triggering a 50cm sea level rise. Other Antarctic glaciers were likely to be similarly unstable. Proceedings of the National Academy of Sciences journal found it was likely to succumb to instability linked to the retreat of its grounding line on the seabed that would lead to it…

The Failure of NASA’s Spacewalk Snafu? How Predictable It Was

When Saralyn Mark heard the news earlier this month that NASA was planning the first all-women spacewalk at the International Space Station on March 29, she started to worry. Mark, an endocrinologist by training, was a senior medical advisor to NASA for 18 years. In that role, she studied the way men and women’s bodies differ, on space and on earth. Within the agency, she advocated for spacesuit and technological design that took these differences to account. She led two separate decadal reviews into how NASA handled sex and gender…

RIP Mars Opportunity Rover. Designed For 90 Days, It Lasted 14 Years

Credits: NASA/JPL-Caltech One of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet. The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity…

What the World Looks Like From the International Space Station

Compiled and edited (and color graded, denoised, deflickered, stabilized) by Bruce W. Berry Jr, all of 4K video and timelapse sequences were taken by the astronauts onboard the ISS (NASA/ESA). In the video description on Vimeo, Bruce adds: Some interesting facts about the ISS: The ISS maintains an orbit above the earth with an altitude of between 330 and 435 km (205 and 270 miles). The ISS completes 15.54 orbits per day around the earth and travels at a speed of 27,600 km/h; 17,100 mph).   The yellow line that…

Mars Lander Captures Haunting Sound of Martian Winds

Listen to Martian wind blow across NASA’s InSight lander. The spacecraft’s seismometer and air pressure sensor picked up vibrations from 10-15 mph (16-24 kph) winds as they blew across Mars’ Elysium Planitia on Dec. 1, 2018. The seismometer readings are in the range of human hearing, but are nearly all bass and difficult to hear on laptop speakers and mobile devices. We provide the original audio and a version pitched up by two octaves to make them audible on mobile devices. Playback is suggested on a sound system with a…

Travelled 300 Million Miles, Took This Pic

NASA/JPL-Caltech The Instrument Deployment Camera (IDC), located on the robotic arm of NASA’s InSight lander, took this picture of the Martian surface on Nov. 26, 2018, the same day the spacecraft touched down on the Red Planet. The camera’s transparent dust cover is still on in this image, to prevent particulates kicked up during landing from settling on the camera’s lens. This image was relayed from InSight to Earth via NASA’s Odyssey spacecraft, currently orbiting Mars. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a…

40 Hilarious Reactions To NASAs InSights First Photos From Mars

This year seems to be quite an active time for all the people who have their eyes set on the “final frontier”.  With Tesla being launched into space, and Kepler’s fuel running out, it was just the time for another big event on the horizon. Launched on the 5th of May, InSight robotic lander has reached the surface of Mars yesterday, November 26, marking another tremendous step in human, as well as space exploration, history. Upon entering Mars’ atmosphere, InSight had reached the speed of  12,300 miles per hour (5.5…

A Real Time 4K Journey Around Earth from Orbit

“Orbit” is a real-time reconstruction of time-lapse photography taken on board the International Space Station by NASA’s Earth Science and Remote Sensing Unit. The structure of the film is built around the world of Phaeleh’s last three albums: Lost Time, Illusion of the Tale, and Somnus. According to the creator, Seán Doran, the tone and pacing of each track influenced the choice of material used. Typically each time-lapse sequence was photographed at 1 frame per second. Each sequence was processed in Photoshop. A dirtmap was made in order to repair…
