2021-05-15 05:30:01 The Starship system is a fully reusable, two‑stage‑to‑orbit super heavy‑lift launch vehicle under development by SpaceX.11 This system is composed of a booster stage named Super Heavy12 and a second stage, also called "Starship."13 Unusual for a traditional space rocket second stage, the Starship second stage is being designed to be a long‑duration cargo and passenger‑carrying spacecraft.

Astronomers using the NASA/ESA Hubble Space Telescope have imaged a Jupiter-sized, still-forming planet around the orange dwarf star PDS 70. This is the first time that an exoplanet has been directly imaged in the ultraviolet (UV).

2021-05-14 15:30:02 Transformation of our Sun into a White Dwarf

Once our sun becomes a Red Giant, it won't be hot enough to ignite the carbon in its core, it will succumb to gravity again. When the core of the star contracts, it will cause a release of energy that makes the envelope of the star expand. Now the star has become an even bigger giant than before, Our Sun's radius will become larger than Earth's orbit!

The Sun will not be very stable at this point and will lose mass. This continues until the star finally blows its outer layers off. The Sun will never fuse carbon however, instead it will shed its outer layers forming a planetary nebula. Our Sun will cool down, radiating heat into space and fading into black lumps of carbon.

The core of the star, however, remains intact, and becomes a white dwarf. This remnant will have a mass of around half that of our present Sun, but will be the size of the Earth.

✧The region of space in which a mass’s magnetic field dominates is known as its magnetosphere. These regions surround planets, pulsars and even our Galaxy.

✧The planets in our Solar System have magnetospheres that interact with and are shaped by the charged particles in the wind streaming from our Sun.

✧The largest magnetosphere in our Solar System surrounds Jupiter. Jupiter rotates very fast and has a very strong magnetic field, and its magnetosphere is filled with plasma from its volcanically active moon, Io.

✧These features, coupled with the fact that the solar wind is slower and less dense at Jupiter than at Earth, lead to a very sizeable Jovian magnetosphere.

✧It is easily big enough to contain a body the size of our Sun and, if visible, would be larger than the Moon in our night sky; quite an achievement considering that it is over 1,500 times farther away.

2021-05-13 23:34:00 The 1825kg Rover+Lander carries a total of 6 scientific instruments to achieve its scientific objectives, which aims to search for evidence of current and past life, produce detailed surface maps of Mars, characterize soil composition and water ice distribution, and examine the Martian atmosphere.

The mission also serves as a technology demonstration that will be needed for the Chinese Mars sample-return mission, which will take place around 2030. Tianwen-1 lander will also cache rock and soil samples for retrieval by the sample-return mission.
