An unusual Phenomenon known as a Red Sprite has been seen by the International Space Station as it orbits the Earth. Seen above a lightning storm, it is unknown what causes this rare phenomena of tendril-like lines that extend up into the atmosphere from the lower storm. The Moon is visible near the centre of the frame, and to its right we can see the constellation of Orion above the atmosphere and lights of our comfortable planet Earth. Along the horizon at the right side of the image is the visible red sprite, occurring quickly during this longer exposure. Amazing...
The rendering I’ve been waiting for is finally here! A conceptual video of the flyby of Pluto from far away, leading through closest approach and turning back to see the dark side, all together. This will give you a sense of the motion of New Horizons, and the state of the Pluto system in the Kuiper Belt. The credit goes not just to NASA, but to space enthusiast Björn Jónsson, who created the rendering from the latest Pluto images and data from New Horizons. The strangest part of watching this was the sense of longing I felt as we fly past...
Occasionally it’s strange to see photos from the Curiosity Rover on Mars. Some of them feel distinctly like home. I can almost imagine a person walking by on the soft sand, through the pathway of rocks, and over the horizon, like a traveller navigating the desert. The latest panorama of Mars gives me that feeling in spades. And yet, this rusty world has too thin an atmosphere to allow a human to breathe. It has no water to drink, and intense radiation from the Sun that prevents life from blanketing its surface. It is human, and yet alien. No homo...
The Deep Space Climate Observatory (DISCOVR) was launched back in February of this year. Although its goal is to measure solar wind particles from the Sun as a space weather predictor, DISCOVR passes the orbit plane of the Earth and the Moon twice per year. In its first pass, it snapped an amazing series of frames of the Moon passing in front of the Earth. The images show the dark side of the Moon, as well as the stark contrast between the darker lunar surface and the bright Earth. The camera that took the shots, the Earth Polychromatic Imaging Camera...
Think about Earth and its population of over 7 Billion people. That’s 7 Billion people who wake up, breathe, live, think, experience, and interact with each other. The sheer volume of interactions and variation in the human experience is staggering. Every second you are alive these interactions are happening all around you, and far from you in any corner of the planet. Millions of people right now feel sad, happy, ecstatic, broken, angry, tired, energetic, and everything in between. Now if we go beyond to the Milky Way, where there are more than 50 stars for each and every homo sapiens on...
Friday’s science update from the New Horizons team shed some more light on the seemingly endless jaw-dropping discoveries from the Pluto system. We have found a surprising atmosphere and very cold ice flows, contributing to a surprisingly active geology for an object that receives so little sunlight. Seven hours after the craft made its closest approach of Pluto, it turned around and took a backlit shot, revealing two distinct layers of hazy atmosphere at 80 Km and 50 Km above the surface respectively. It looks more like an eclipse photograph from much closer to home, but it shows a hauntingly...
The surface of the Sun is around 5500 degrees Celsius. It’s hot, and it’s a completely different state of matter than the solid, liquid, and gas states that we are used to. However, this is a pretty balmy temperature compared to the solar atmosphere, which is heated to over a million degrees. But how does it get so hot compared to the surface? We know the core of the Sun, where fusion happens, is where temperatures can reach 14 Million degrees, but how is that energy radiated outward? And more importantly, how does it bypass the solar surface and make...
Not one person’s mom, but specifically an entire nation’s. India’s Mars Orbiter Mission is lovingly known as MOM and has been sending back science data that has put India on the Space Exploration Map, if there ever was one. The Indian Space Research Organization (ISRO) launched the ambitious but cost-effective MOM Orbiter on November 5th, 2013. With a bill of only 73 Million dollars, its the most cost-effective Mars mission ever, yet its sending back lovely images and science data that is worth every penny, at least to a biased spaceflight enthusiast such as myself. Whatever you feel about the...
Auroras on Earth are caused by the ionization of atoms high in the atmosphere near the north and south magnetic poles. The solar wind flies toward the Earth and this harmful radiation is blocked and funnelled by our magnetic field, creating harmless, beautiful glows that remind us how close we came to total destruction, but were saved by our planet. Do other planets have auroras? Certainly! Jupiter and Saturn do, and even moons like Ganymede can have auroral activity. It really depends on the magnetic field. So how does a planet like Mars, with no magnetic field, have auroras? This...
Eight minutes after launching from the Baikonur Cosmodrome, a Russian Proton-M rocket experienced a catastrophic failure in its third stage rocket, resulting in the complete atmospheric burn-up of the rocket and its payload, a Mexican Communications Satellite. After launching at 11:47am local time in Kazakhstan, the rocket experienced an emergency situation 497 seconds into the flight, reported as a failure in the rocket’s Breeze-M third stage. The carrier rocket was launching the Mexsat 1 communications satellite, known as Centenario, into orbit, in a contract with the Mexican government. After reaching a 161 Km altitude, the rocket failed and fell back to...
