What a shot

my second attempt at star trails, any tips on how to improve would be appreciated

There’s a meetup happening in the western sky: the crescent Moon sits close to Jupiter, with Venus below them. Jupiter and Venus will continue to cozy up until March 1, when they’ll be at their closest. Have you spotted these three in the sky? Snap a picture and send it to us! https://t.co/8W1iihFz3w

Yellow moon I photographed with my camera

The @SpaceX #Crew6 members are at @NASAKennedy preparing to launch to the station early next week. Meanwhile, the Exp 68 crew is studying space botany on the orbiting lab. #SpaceToGround https://t.co/n4EusdkU1K

Can anyone tell me what the body is below the Moon? I know Venus and Jupiter line up with the Moon lower, but when i opened up the picture i noticed a third body.

Lifeboat Liftoff (OC)

The #MarsHelicopter will attempt Flight 46 as early as tomorrow, Feb. 25. It is expected to fly 1,461 feet (445 m) southwest to reposition itself and scout for future airfields. If successful, this will be Ingenuity's 4th flight in 10 days! 🚁 https://t.co/ll6tXnTgCe

Scientists find meteorite in Texas from fireball that exploded with the force of 8 tons of TNT https://t.co/Lj6MsjyDgS https://t.co/obhkIwxjcF

This week, the @Space_Station crew used the Astrobee robots to demonstrate hopping maneuvers that use less propellant and could advance ground robotics. The team also evaluated the mental health benefits of growing plants on station and more! https://t.co/ihxCFPzSVr https://t.co/fEw8xwkU49

Why do you get the same mass of Jupiter regardless which of Jupiter's moons you use to calculate it (i.e Io, Ganymede, Callisto, Europa)?

I'm not if this is the right sub to be posting this type of question, but to calculate mass of Jupiter, you can use the equation M=a\^3/P\^2, with M = the mass of the bigger object (Jupiter) (in kilograms), a = the semimajor axis/radius of the smaller object (moon) (in AU), and P = orbital period of smaller object (moon) (in years). I get about the same number regardless of which of the moons' radius and period I plug into the equation. Why is that?

How is it possible to see the band of the milky way Galaxy in the sky at night?

I saw it when I was in death valley but it brought some questions. What makes it possible to see the milky way band? What are the cloudy parts in the band? Thanks to anyone who can answer.

#Crew6 prepares to head to the @Space_Station, @ChandraXray spots two supermassive black holes on a collision course, and @NASAPersevere begins its third year on Mars. Subscribe for all this and more, this week at NASA: https://t.co/Yow4nHcNTX https://t.co/LVjyscaBfw
