A 最高の-Earth covered in oceans of 溶岩 and another exoplanet that is 完全に airless have been chosen as the first 的s of 航空宇宙局's James Webb Telescope.?

One of the 惑星s, known as?55 Cancri e, has surface 気温s reaching 4,400 °F (2,400?°C) ? far above the melting point of typical 激しく揺する-forming minerals.

The day 味方する is thus thought to be covered in 溶岩, which could also 落ちる as rain depending on its 軌道ing pattern.

The rocky 惑星 has a 直径 almost twice that of Earth and is therefore known as a '最高の-Earth' ? meaning it is larger than our 惑星 but smaller than Neptune.

It 軌道s?いっそう少なく than 1.5 million miles from its Sun-like 星／主役にする ? one twenty-fifth of the distance between 水銀柱，温度計 and the Sun?? and 完全にするs one 回路・連盟 in いっそう少なく than 18 hours.

The telescope will also 観察する LHS 3844 b, which 軌道s a 星／主役にする that is smaller and cooler than 55 Cancri e's host 星／主役にする.

This 惑星 is not hot enough for its surface to be molten, and is ありそうもない to have a 相当な atmosphere, meaning scientists can analyse the solid 激しく揺する on its surface.?

The Webb telescope now を待つs a final 器具 calibration before it 公式に begins 熟考する／考慮するing distant 星／主役にするs and 惑星s next month, like?55 Cancri e and?LHS 3844 b

The?$10 billion James Webb Space Telescope is 現在／一般に about 1,500,000 kilometres away from Earth after it was 開始する，打ち上げるd in December 2021.

With its 器具s 提携させるd, the Webb telescope now を待つs a final 器具 calibration before it 公式に begins 熟考する／考慮するing distant 星／主役にするs in a few weeks time.

航空宇宙局 研究員s will train the onboard, high-precision spectrographs の上に?55 Cancri e to understand its 地質学.

This will give an insight into?the geologic 多様制 of 惑星s across the 星雲, and the 進化 of rocky 惑星s like Earth.

惑星s that 軌道 very の近くに to their 星／主役にする, like 55 Cancri e, are thought to be tidally locked and have one 味方する 直面するing the 星／主役にする at all times.

潮の locking happens because both 天文学の 団体／死体s 発揮する gravitational 軍隊 on the other, which is stronger on the 味方するs 直面するing each other.

This 軍隊 原因（となる）s the 軌道ing 団体／死体 to stretch and distort, which in turn slows 負かす／撃墜する its rotation.

結局 it is slowed 負かす／撃墜する to the point that the 速度(を上げる） of the 惑星's 軌道 and its rotational 速度(を上げる） match, and one 味方する only ever 直面するs the 星／主役にする ? just as only one 味方する of the Moon ever 直面するs Earth.

The hottest 位置／汚点／見つけ出す on the 惑星 should be the one that 直面するs the 星／主役にする most 直接／まっすぐに, and the 量 of heat coming from the day 味方する should not change much over time.

However, 観察s of 55 Cancri e?from 航空宇宙局’s Spitzer Space Telescope 示唆する that the hottest 地域 is 相殺する from the part that 直面するs the 星／主役にする most 直接／まっすぐに, and the total 量 of heat （悪事，秘密などを）発見するd from the day 味方する 変化させるs.

One explanation for this 現象 is that the 惑星 has its own dynamic atmosphere that moves the heat around.

研究員s will use Webb’s 近づく-Infrared Camera (NIRCam) and 中央の-Infrared 器具 (MIRI) to 逮捕（する） the thermal 放出／発行 spectrum of the day 味方する of the 惑星.

Renyu Hu, from NAS A’s Jet Propulsion 研究室／実験室 in California, said: '55 Cancri e could have a 厚い atmosphere 支配するd by oxygen or 窒素.

'If it has an atmosphere, [Webb] has the sensitivity and wavelength 範囲 to （悪事，秘密などを）発見する it and 決定する what it is made of.'

However,?55 Cancri e may not be tidally locked at all, and could 回転／交替 three times for every two 軌道s, as 水銀柱，温度計 does, meaning it has a day-night cycle.

Alexis Brandeker,?研究員 from Stockholm University who leads another team 熟考する／考慮するing the 惑星, said: 'That could explain why the hottest part of the 惑星 is 転換d.

'Just like on Earth, it would take time for the surface to heat up.?

'The hottest time of the day would be in the afternoon, not 権利 at noon.'

Brandeker’s team 計画（する）s to 実験（する） this hypothesis using NIRCam to 手段 the heat emitted from the lit 味方する of 55 Cancri e during four different 軌道s.?

If the 惑星 does 回転／交替 three times for every two 軌道s, they will 観察する each 半球 twice and should be able to （悪事，秘密などを）発見する any difference between the 半球s.?

In this シナリオ, the surface would heat up, melt, and even vaporise during the day, forming a very thin atmosphere that the James Webb Space Telescope could （悪事，秘密などを）発見する.?

Then, in the evening, the vapour would 冷静な／正味の and condense to form droplets of 溶岩 that would rain 支援する to the surface, turning solid again as night 落ちるs.

The James Webb Telescope is ーするつもりであるd to 後継する the Hubble Space Telescope as 航空宇宙局's 旗艦 使節団 in astrophysics.

It is composed of 18 hexagonal mirror segments, fitted together into one large, 21-foot-wide mirror.

During its １０年間 or more in 軌道, Webb will be used by teams of 天文学者s to 熟考する／考慮する a wide variety of celestial phenomena, from exoplanets to 黒人／ボイコット 穴を開けるs.

It is able to peer その上の into the history of the universe than any space telescope before it, in part 予定 to its position 930,000 miles from the Earth.
