Thirty years ago, astronomers had discovered that the only planet in our sun was here. The galaxy is full of planets with millions of human-like suns. However, it is well known that there is a blank space for understanding other star systems in the world.
According to reports, as the exploration of the planet began in 2014, astronomers not only discovered that more than a thousand "exoplanet planets" were orbiting distant stars, but also the beginning of human beings began to make accurate measurements. Ballard said that endless exoplanets are filling data, and the data can be accurate to the second decimal place. It does look amazing.
By Sarah Ballard, a NASA researcher at the University of Washington at Carl Sagan, a team of researchers at the University of Seattle in Seattle, recently measured the "Super Earth," whose diameter of 148 miles, the precision of observation accuracy is shown on the outer planets About 300 light-years of location.
First of all, from the earth's perspective, Kepler found the planet, Kepler 93 B passed directly in front of the star, causing the star to dim during transit. The dimming occurs every time this track. In Spitzer and Kepler's recording of multiple transits in the visible and infrared data consistent with the observed data, it is clear that Kepler 93B is a true planet, not an illusion of stellar variation. Ballard later calculated the size of the planet relative to the star by carefully observing the light curve. At this point, the only missing part is the diameter of the star itself.
He said that most people have heard of "earthquakes." Seismic waves have been derived from studies of Earth movements. We can learn a lot about the structure of our planetary seismic waves. Ballard’s colleague, by analyzing the stellar seismic pattern, can infer the accuracy of its radius and percentage of mass.
The new measurement confirms that Kepler 93b is a super-Earth that is about twice as large as Earth. Kepler 93B, previously measured in Hawaii, is about 3.8 times the Earth. Kepler 93B's quality derives a new radius, and density indicates that the planet is likely to be made of iron and rock.
The vacuum bags are popular because they allow you to preserve your foods to perfect condition, which works together with vacuum sealers machine, no matter dry foods or wet foods, it always keeps your meal longer so you don't waste it.
One side embossed channel and transparent on the other, provide strong suction and sealing, keep food from puncturing the vacuum bag. Visible design makes it better display of the food in the bag.
Compatible with all Vacuum Sealer machines, with tight edge and smooth sealing, which provide better insulation from air.
