STS-ninety nine also noticed the recommissioning on the Spacelab pallet procedure, Regardless of the Spacelab technique currently being discontinued Practically two a long time prior.
Many unexplained phenomena in M99 are actually examined by astronomers. Amongst these is the character of PTF 10fqs — among the list of brighter stars Within this image and visual as a yellow-orange star in the top-still left corner. Exactly what is abnormal about PTF 10fqs is usually that it's got thus far defied classification. When it had been discovered in April 2010, it appeared brighter than the usual nova (attributable to an eruption with a star’s floor) but fainter than a supernova (the explosion that marks the top of life for a significant star).
The Shuttle Radar Topography Mission mast was deployed productively to its complete duration, as well as antenna was turned to its operation placement. Immediately after An effective checkout with the radar techniques, mapping began at 12:31 a.
Hello, I’m Doug Rowland. And that i’m a scientist finding out the Earth’s higher environment. And that’s an interesting area, since it’s the place the Earth’s environment that we breathe, turns into a gas known as plasma that’s electrically charged.
My name is Don Gurnett. I’m an emeritus professor within the University of Iowa Division of Physics and Astronomy, where I’ve labored for anything near 65 a long time. I’ve been other destinations between, though.

HOST PADI BOYD:Right now, we are having you over a tour of plasma – what it really is and in nasa99 which we can discover it. But in advance of we get out while in the expanses of Area, we have to start out actually, truly compact…
HOST PADI BOYD:As we continue on out on our plasma journey, the most vital supply of plasma within our solar method… may be the Sunlight.
If you might strip the electron off on the atom so the electrons are absolutely free, Then you really have electrons and positive ions, that’s called a plasma.
During the day there’ll be plasma at People altitudes, Which’s generated because the daylight shines on that fuel. It’s very tenuous gas. So there’s sunlight shines on it, the ultraviolet gentle breaks Those people atoms aside.
This graphic, taken by the NASA/ESA Hubble House Telescope, reveals an in depth check out in the spiral arms on a person side from the galaxy Messier ninety nine. Messier ninety nine is often a so-referred to as grand design and style spiral, with very long, massive and Obviously defined spiral arms — supplying it a framework considerably much like the Milky Way. Lying all-around 50 million light-weight-yrs away, Messier ninety nine is among more than a thousand galaxies that make up the Virgo Cluster, the closest cluster of galaxies to us. Messier ninety nine itself is relatively shiny and huge, meaning it had been one of many first galaxies to generally be uncovered, way back from the 18th century. This attained it a location in Charles Messier’s popular catalogue of astronomical objects. In recent years, a variety of unexplained phenomena in Messier 99 are researched by astronomers. Between these is the nature of among the list of brighter stars visible With this image. Catalogued as PTF 10fqs, and visible to be a yellow-orange star in the very best-remaining corner of the image, it had been to start with spotted because of the Palomar Transient Facility, which scans the skies for unexpected adjustments in brightness (or transient phenomena, to employ astronomers’ jargon).

HOST PADI BOYD:Each day, you can find plasma in fluorescent lightbulbs, plasma display Television set’s, and neon indicators… but they are pretty modest and contained cases.
HOST PADI BOYD: A lot of interstellar Place – the distances amongst solar systems – is stuffed with hydrogen and helium plasmas.
