Using an instrument called a coronagraph, JWST will try to determine whether a planet has an atmosphere,
Magnetic field lines extend from the solar surface all the way into the corona. Moving and twisting bundles of field lines form magnetic flux tubes.
he system is turbulentthe magnetic field lines in the corona do not move in a random pattern
and other telescopes to make fascinating new observations including using MKIDS coupled to a coronagraph to directly discover
For decades, researchers have suspected that powerful magnetic fields are heating the corona. The Sun's atmosphere is just jam-packed full of magnetic field,
they push and pull the charged gas in the corona, giving it the energy that heats it up.
a camera capable of taking pictures of the Sun's corona in fine detail. The imager was placed on board a research rocket at the White sands Missile Range in New mexico
Theorists had suggested an escape route for the protoplanets. Their idea was that pressure differences in the disc could spontaneously create vortices trapping the larger dust grains
But is the strange structure really helping to build protoplanets? It is quite far from the star
These loops form a new layer surrounding the nanotube, known as a corona. The MIT researchers found that the loops within the corona are arranged very precisely along the tube,
and the spacing between the anchors determines which target molecule will be able to wedge into the loops
They are now working on a way to predict such polymer-nanotube interactions based on the structure of the corona layers,
using data generated from a new type of microscope that Landry built to image the interactions between the carbon nanotube coronas
and their targets. hat happening to the polymer and the corona phase has been a bit of a mystery,
or all protoplanetary disks around forming stars study author Conel Alexander explained in a press release.##The researchers concluded that a significant portion of Earth s water came from interstellar space by looking at the relative abundance of hydrogen and deuterium.#

the whole accretion disk made of surrounding hot gas would glow in ultraviolet rays. Instead, the ultraviolet glow of the dusty disk abruptly drops off toward the center.

who led the WISE study and whose previous work identifying recycled planetary dust, known as debris disks, around close to a hundred other star systems, puts the discovery of the exoplanet in context.
his team has provided the astronomers with geometric phase holograms that they have used build advanced coronagraphs--telescopes that can see things close to stars--to study exoplanets beyond our solar system."

The coronagraph is represented by the black filled circles. he Gemini Planet Imager allows us to study nearby planet forming disks in sufficient detail that we can obtain direct-image evidence for young planets in orbits similar to those of the giant planets
