1578 -Tycho Brahe first sketches “Tychonic system” of the solar system
On February 13, 1578, Tycho Brahe, a Danish astronomer put forward his idea of the Solar system. All the planets orbit the Sun (except the Earth) and the Sun and Moon orbit the Earth. So to sum up the Earth alone is fundamentally at rest in the Tychonic system. The modification of this theory in comparison to its predecessors is that this was able to explain the variations in phases of venus. The Tychonic system is useful for astronomers today as an observational perspective since the Earth is our observing platform.

2004 – Discovery of the universe’s largest known white dwarf star BPM 37093.
The constellation Centaurus is home to the white dwarf BPM 37093. Making it the largest known star to date, this dwarf weighs 5 million trillion trillion pounds.

2019 NASA confirms Mars Opportunity rover’s mission has ended after 15 years due to sandstorm damaging communications
The Opportunity rover worked on Mars from January 2004 through 2019, when a monster sand storm stilled it for good. Originally intended to last 90 days, this machine lasted well up to 15 years of its lifetime. It used panoramic cameras to take the images combined into a mosaic view of the rover. Though an end, this feels like a milestone in discovering life on the other planet. One of the important observations of Opportunity was verifying the appearance of water on Mars for extended periods.
