Scientists say the James Webb Telescope, a space telescope, will observe 55 planets E and LHS 3844 B without air outside our solar system.
The James Webb Telescope space telescope will observe two warmer 'super-Earth' planets, one of which once had lava seas.
NASA has announced that research to be published this summer will focus on two rocky planets: the lava-covered 55 Canary E and the airless LHS 3844B.
Orbiting 1.5 million miles (2.4 million kilometers) away from its Sun in space, 55 Cancari E has a year of only 18 hours. One side of this planet is always facing its sun, which is called 'tidal lock'. From this, it can be concluded that the temperature of the planet should be relatively uniform.
However, in the case of 55 Cancer E, this does not seem to be the case, since the hottest part of the world is in the opposite direction to the part facing the sun.
One explanation for this may be that there is a dynamic atmosphere in this strange world that transmits heat.
Reno Ho, of NASA's Jet Propulsion Laboratory in Southern California, explained: If there is an atmosphere in it, [the web] has the sensitivity and wavelength to determine what the atmosphere is made of.
Another suggestion is that the 55 Cancri e Tidally Lock (as the Moon is locked to the Earth and its only side is always in front of the Earth). Instead, it may act like Mercury, which rotates three times on its axis every two cycles around the Sun, thus transmitting temperatures.
Alexis Brandicker, a researcher at Stockholm University, explains: 'This may explain why the warmest part of the planet is on the other side. Like the earth, it takes time for the surface to warm up. The hottest time of the day will be in the afternoon, not at noon.
Scientists plan to measure the temperature at four different orbits on 55 Cancari E with the hope that during the day the surface will heat up, melt and possibly evaporate, causing There will be a very thin atmosphere that the web telescope can detect.
In the evening, the vapor cools and thickens to form lava droplets that fall back to the surface and solidify again at night.
The other planet, LHS 3844B, does not have such a temperature due to its relatively small size - but it will certainly allow scientists to analyze solid rock on another planet, as the planet is unlikely to have a thick atmosphere. ۔
Laura Kredberg of the Max Planck Institute for Astronomy explained: 'Different types of rocks have been shown to have different spectra. You can see with your own eyes that the color of granite is lighter than basalt. The infrared rays emitted from the rocks are similarly different.
The team will record the thermal emission spectrum on the day of LHS 3844B and then compare it with the spectra of known rocks such as basalt and granite to determine its composition.
These observations will help scientists to understand what the earth was like in the beginning and to find new information in the search for another world.
At present, more than 5,000 exoplanets (planets outside our solar system) have been discovered in our galaxy, and scientists believe that there may be hundreds of billions of exoplanets in total. Life may exist on some of these billions.
