The year on these planets lasts 11 and 18 hours. James Webb to explore two super-Earths this year
The James Webb Space Telescope will study completely different objects, and among others there will be exoplanets.
As it became known, one of the goals for the first year of work will be two super-Earths located about 50 light years from Earth.
The exoplanets 55 Cancri e and LHS 3844 b share a class (these are super-Earths, that is, rocky planets are noticeably larger than the Earth) and the fact that they orbit very close to their parent stars. But the conditions on these planets, according to available data, are very different.
55 Cancri e is less than 2.4 million km from the star. For comparison, the diameter of the Sun is almost 1.4 million km. A year on this planet lasts less than 18 hours, and the temperature on the day side is such that there should be one continuous ocean of lava. At the same time, scientists believe that the planet is in tidal capture, that is, it always faces the star on one side. And this means that on the other side it is always night and much colder.
Observations of the exoplanet have led scientists to speculate that it has a dense atmosphere of oxygen and nitrogen that moves heat from the day side to the night side. Although there is another theory that takes into account the possibility of rotation of the planet. In this case, it should rain from lava. In any case, the James Webb telescope has the tools to better understand 55 Cancri e.
LHS 3844 b has been observed to have no atmosphere. At the same time, the year on this planet is even shorter – only 11 hours. But since the parent star is much smaller and colder, the surface of LHS 3844 b does not melt. This will allow astronomers to study the composition of the rocks of the exoplanet (through spectrography).
The James Webb team says the telescope is weeks away from being fully operational.

Tomorrow NASA will launch the Capstone spacecraft to the moon. It will allow to calculate the orbit for the future American lunar station Gateway
The US National Aeronautics and Space Administration has postponed the launch of the Capstone spacecraft from June 27 to June 28. The reason for the postponement of the launch is to conduct a “final check of the systems” of the launch.
Capstone should help calculate the orbit for the future lunar station Gateway. The spacecraft weighing about 25 kg is planned to be launched from Rocket Lab’s spaceport in New Zealand. NASA believes that Capstone will reach the goal in three months and spend at least six months in orbit. The space department indicates that the Capstone trajectory scheme is such that the device will arrive in its lunar orbit on November 13, regardless of the launch date “in the current period” – which is any day before July 27.

Unique on the outside and simple on the inside. Nothing Phone (1) specs leaked before announcement
Although the new Nothing Phone (1) smartphone is already available for pre-order in India, the developers have not yet confirmed its specifications.
Nothing is said to be in talks with Reliance Digital to sell the Nothing Phone (1) in its retail stores. The expected characteristics of the device were also published.
Nothing Phone (1) will receive a FullHD + OLED screen with support for a refresh rate of 120 Hz. It will be built on the basis of a Snapdragon 778G + single-chip system, the amount of RAM will be 8 GB.
The main camera will be equipped with image sensors with a resolution of 50 and 16 megapixels, the front camera will be 16 megapixels. The battery capacity will be 4500 mAh, it will support 45-watt charging.
The smartphone will run on the Android 12 operating system with the Nothing OS shell and proprietary Glyph Interface installed.
The presentation of Nothing Phone (1) is expected on July 12th.
Images of the GeForce GTX 1630 graphics card have appeared on the Web, which should hit the market tomorrow if Nvidia does not postpone the launch again.
The model is very similar to MSI cards, but this device is from Colorful. The adapter of the BattleAx line received a cooling system with a pair of fans, but the radiator does not have a single heat pipe. However, given the parameters of the GTX 1630, its power consumption will be low.
Ports include HDMI, DisplayPort, and the now rare DVI. To work, the card still requires a six-pin power connector.
Recall that the new Nvidia is based on the TU117 GPU with 512 CUDA cores. She also received 4 GB of memory and a 64-bit bus. The adapter is expected to be even slightly slower than the GTX 1050 Ti.
