Citar
A hot, rocky “super-Earth,” near one of the oldest stars in the galaxy has taken a team of planet-hunting scientists by surprise.

The planet is about 50 per cent larger than Earth but requires less than half a day to orbit its star.

Private spaceflight companies soar while SLS remains grounded
In the spaceflight world, Virgin Orbit and SpaceX continued to dazzle. Meanwhile, NASA and Boeing’s Space Launch System continue to disappoint.

Virgin Orbit’s LauncherOne as it released its rocket at an altitude of 35,000 feet. Once the rocket was let go, it began its own journey to space where it released the 10 satellites it was carrying to space.

Astronomers are studying the atmospheres of faraway planets
How’s the weather up there? Even for exoplanets that are many light-years away, astronomers can learn about their atmospheres.

https://www.technology.org/2021/01/26/the-7-rocky-planets-orbiting-trappist-1-may-be-made-of-similar-stuff/

Citar
The TRAPPIST-1 star system is home to the largest batch of roughly Earth-size planets ever found outside our solar system. Discovered in 2016 some 40 light-years away, these seven rocky siblings offer a glimpse at the tremendous variety of planetary systems that likely fill the universe.

A study accepted by the Planetary Science Journal shows that the planets share similar densities. That could mean they all contain roughly the same ratio of materials thought to be common to rocky planets, such as iron, oxygen, magnesium and silicon. If so, then while the TRAPPIST-1 planets might be similar to each other, they appear to differ notably from Earth: They’re about 8% less dense than they would be if they had the same chemical composition as our planet.

Summary:
Scientists have just shown that the influence of Saturn's satellites can explain the tilt of the rotation axis of the gas giant. Their work also predicts that the tilt will increase even further over the next few billion years.

Citar
WASHINGTON — SpaceX successfully launched another set of Starlink satellites Feb. 4 in the first of back-to-back Falcon 9 launches scheduled from Cape Canaveral.

The Falcon 9 rocket lifted off at 1:19 a.m. Eastern from Space Launch Complex 40 at Cape Canaveral Space Force Station. Its payload of 60 Starlink satellites separated from the rocket’s upper stage 65 minutes later.

The rocket’s first stage landed on a droneship in the Atlantic Ocean eight and a half minutes after liftoff. The booster was on its fifth flight, having been used most recently for the launch of the Turksat 5A satellite Jan. 8.
