Spiral Galaxy NGC891 New Edit

I used a different way of editing my pictures; mainly converting is changed. I converted the fts files to tiff32 rational using DeepSkyStakker and made editing possible into CS4.
The result is much better then starting within tiff16.

Parker Solar Probe Breaks Record and Becomes Closest Spacecraft to Sun

After the first gravity assist on October 3rd, 2018, between Parker Solar Probe and Venus, the Parker Solar Probe now holds the record for closest approach to the Sun by a human-made object. Parker Solar Probe passed the current record of 42.72 million km from the Sun's surface on Oct. 29, 2018, at about UT17:04, as calculated by the Parker Solar Probe team.

Over the next years the probe will continue to break it's own records as it will fly closer and closer to the Sun.
