The Juno mission has been revealing angles of Jupiter we’ve never seen before. This photo shows Jupiter’s northern temperate latitudes and NN-LRS-1, a.k.a. the Little Red Spot (lower left), the third largest anticyclone on Jupiter. The Little Red Spot is a storm roughly the size of the Earth and was first observed in 1993. As an anticyclone, it has large-scale rotation around a core of high pressure and rotates in a clockwise direction since it is in the northern hemisphere. Jupiter’s anticyclones seem to be powered by merging with other storms; in 1998, the Little Red Spot merged with three other storms that had existed for decades.

SpaceX has plans to send two private citizens around the Moon, CEO Elon Musk announced today.
It will be a private mission with two paying customers, not NASA astronauts, who approached the company. The passengers are “very serious” about the trip and have already paid a “significant deposit,” according to Musk. The trip around the Moon would take approximately one week: it would skim the surface of the Moon, go further out into deep space, and loop back to Earth — approximately 300,000 to 400,000 miles.
The plan is to do the trip in the second quarter of 2018 on the Crew Dragon spacecraft with the Falcon Heavy rocket, which is due to do its maiden launch this summer. Of course, Musk is well-known for his unrealistic deadlines — in 2011, he promised to put people in space in just three years.
The two people going on the trip, who weren’t named, already know each other. They will begin initial training for the trip later this year. Musk declined to comment on the exact cost of the trip, but said it was “comparable” or a little more than the cost of a crewed mission to the International Space Station. For context, one ticket on the Russian Soyuz rocket costs NASA around $80 million.

When scientists get too honest

We all know this struggle, Cylinder. We all know. March 4, we make their dreams come true on YouTube! Tune in!
It was a bad conductor
The cloud chamber, also known as the Wilson chamber, is a particle detector used for detecting ionizing radiation.
In its most basic form, a cloud chamber is a sealed environment containing a supersaturated vapor of water or alcohol. When a charged particle (for example, an alpha or beta particle) interacts with the mixture, the fluid is ionized. The resulting ions act as condensation nuclei, around which a mist will form (because the mixture is on the point of condensation).
The high energies of alpha and beta particles mean that a trail is left, due to many ions being produced along the path of the charged particle. These tracks have distinctive shapes, for example, an alpha particle’s track is broad and shows more evidence of deflection by collisions, while an electron’s is thinner and straight. -(x)
