Phosphine(PH3) gas discovered on Venus.

Its interesting because PH3 is a bio signature. And this might indicate the presence of some kind of life in the clouds of Venus.

Space officially begins at the universal marker of the Karman Line. This invisible boundary is 100km above the Earth.

The line is named after Theodore von Kármán (1881–1963), a Hungarian-American engineer and physicist, who was active primarily in aeronautics and astronautics. He was the first person to calculate that the atmosphere around this altitude becomes too thin to support aeronautical flight, since a vehicle at this altitude would have to travel faster than orbital velocity to derive sufficient aerodynamic lift to support itself.

In a vacuum like space, when two pieces of metal touch each other they bond together. This is a process called cold welding. On the Earth because of the oxygen in our environment this does not happen naturally but it is used during some manufacturing processes

The North Star used for navigation, a steady point in the night sky will change, however not in our lifetime.
The Earth is rotating like a spinning top and therefore the pole of our planet wobbles. Currently it points to Polaris but in the year 13727 our Pole Star will be the star Vega, in the constellation of Lyra. Vega was the also North Star in 12000BCE

A year on Venus is shorter than its day.
Venus is the slowest rotating planet in our Solar System, it rotates in a period of 243 days while it take 224.8 Earth days to revolve around Sun.

this will be the view of night sky 3.75 billions years from now from Earth , after 7 billions years from now cores of and will marry and Eath will be step child of a new galaxy .

this is now you on earths surface are moving through universe aboard spaceship Earth in direction of constellation Leo and Virgo are at speed of 2.1 million km/hour .
this is path .
this is roughly 100 years of earths movement is 100 years .
YOU DIN'T BUY TICKET FOR THIS RIDE , YOUR PARENTS SIGNED YOU UP WITHOUT ASKING YOU , BUT QUITE LITERALLY "IT IS RIDE OF OUR LIFE".

Bye MESSENGER.

The robotic spacecraft MESSENGER has run out of fuel. With no way to make major adjustments to its orbit around the planet Mercury, the probe will smash into the surface at more than 8,750 mph (3.91 km/s). The impact will add a new crater to the planet's scarred face that engineers estimate will be as wide as 52 feet (16 meters).

The end is predicted to come at about 3:26 p.m. EDT today.

Astronomers have revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole.
