First View of ‘Interplanetary Shock’ Spotted by NASA Spacecraft

This entry was posted in Interesting Phenomena on by .

The spacecraft comprise a NASA project called the Magnetospheric Multiscale mission, nicknamed MMS, which launched in 2015. The mission is focused on studying the magnetic environment surrounding Earth. To do so, it relies on four identical spacecraft that cooperate to map what’s happening.

In new research, scientists dissect a particularly intriguing phenomenon that occurred in the magnetic field in January 2018. Because the individual satellites were deployed within just 12 miles (20 kilometers) of each other, they got a prime view of what was happening.

ExoMars radio science instrument readied for Red Planet

The latest testing of LaRa took place in ESA’s Mechanical Systems Laboratory (MSL) at the Agency’s ESTEC technical heart in Noordwijk, the Netherlands. This is a small-scale version of the adjacent ESTEC Test Centre, able to perform a wide range of space-simulating tests, but serving spacecraft instruments, subsystems or mini-satellites rather than full-size missions.

Following vibration testing on one of the MSL shaker to simulate the harsh conditions of launch, atmosphere re-entry, descent and Mars landing, LaRa was then placed inside a thermal vacuum chamber for nearly two weeks to perform functional testing in hot and cold conditions.

NASA’s Spitzer just spotted a galaxy perfectly aligned with Earth

NASA’s Spitzer Space Telescope is capable of capturing some truly stunning snapshots of distant features in space, and usually, when we see images of vast spiral galaxies we get to see them face-first. First View of 'Interplanetary Shock' Spotted by NASA ... View of 'Interplanetary Shock' Spotted by NASA Spacecraft A team of four NASA spacecraft finally caught sight of a phenomenon scientists have been hunting for years: an interplanetary shock.... A new photo shot by Spitzer of a distant galaxy called NGC 5866 is much different, but no less interesting.

We don’t really get to choose the angle at which we see distant galaxies, so astronomers can only work with what they’re given. NASA finds evidence of 'interplanetary shock' for first ... interplanetary shock, which emanates from the Sun, is a type of "collisionless shock," where particles transfer energy through electromagnetic fields as opposed to bouncing into one another,... In this case, galaxy NGC 5866 is positioned so that we’re seeing only its edge, making it look like a giant glowing splinter in space.

Ancient, ‘invisible’ galaxies from beginning of the universe spotted for the first time

While the researchers can’t tell exactly how old the galaxies are or what makes them up, they will shift the current understanding of galaxy evolution. NASA’s MMS Finds Its 1st Interplanetary Shock | NASA MMS mission just made the first high-resolution measurements of an interplanetary shockwave launched from the Sun. The amount of mammoth, dust-filled galaxies observed exceeds what was expected with our current models of the universe, challenging the current hypotheses of how these massive galaxies evolve.

Their discovery also opens up the possibility of studying other cosmic phenomena such as supermassive black holes, which scientists know reside in the center of big galaxies, and also the enigmatic dark matter, theorized to make up the majority of matter in our universe.
