The Juno spacecraft began its long journey to Jupiter in 2011. Waking up in 2016 it underwent a successful orbit injection on July 4th. Now after nearly a year of waiting, the public finally gets to see the first fruits of the mission. It has certainly been worth the wait. A new Jupiter, seen from a distance of 52,000 Km, has a vivid and chaotic southern pole in the above image. Swirling storms thousands of kilometres across whirl around one another in a sea of gaseous ammonia clouds. Will the system remain chaotic? Or will it change a year from...
One of the most important questions our species has tackled is the origin of life on Earth. If we can figure out the conditions and catalyst for the beginning of life, we can look elsewhere in the universe for those same conditions, and zero in on the potential for finding extraterrestrial life. We know the universe is old enough for the painstakingly slow evolutionary process, but what started it? In the famous 1952 Miller-Urey experiment, a flask containing the basic natural elements water (H20), methane (CH4), Ammonia (NH4), and Hydrogen (H2), all present on the early Earth, was subjected to...
If there’s one true fact about every single gas giant planet ever observed, around the Sun or other stars in the Galaxy, it’s that they all are mainly composed of Hydrogen. Even though the giants of our solar system such as Neptune and Jupiter seem very different, it is Hydrogen that primarily composes them. The difference is in the details though. The blue colour of Neptune is due to the presence of Methane, and even then it only makes up 1.7% of Neptune’s mass. But Hydrogen is light. Wouldn’t giant planets like hot Jupiters lose their Hydrogen from being blasted...
This morning at 4am EST on the International Space Station, an Ammonia leak alarm went off, leading the crew to perform an emergency evacuation from the American capsule of the ISS. All of the astronauts are currently safe and secure in the Russian capsule of the ISS. The hatch between the two capsules has been sealed, and any non-essential equipment has been powered down. Mission Control is in the process of assessing whether the alarm was the result of an actual leak or a malfunction, though recent reports from NASA TV suggest that the alarm was due to computer glitch...
