In the format DD/MM/YY.
There is no special meaning or superstitious interpretations for this day. This remark is just for fun.

Sagittarius A* (pronounced "Sagittarius A-star", standard abbreviation Sgr A*) is a bright and very compact astronomical radio sourceat the center of the Milky Way, near the border of the constellations Sagittarius andScorpius. It is part of a larger astronomical feature known as Sagittarius A. Sagittarius A* is thought to be the location of asupermassive black hole, like those that are now generally accepted to be at the centers of most spiral and elliptical galaxies. Observations of the star S2 in orbit around Sagittarius A* have been used to show the presence of, and produce data about, the Milky Way's central supermassive black hole, and have led to the conclusion that Sagittarius A* is the site of that black hole.

IC 2944 è una nebulosa a emissione nella costellazione del Centauro, a 5.900 anni luce di distanza. Contiene due delle prime dieci stelle più luminose dell'universo, produttrici di enormi quantità di potenti radiazioni UV. Un aspetto interessante di questa nebulosa è la presenza di globuli scuri, detti “globuli di Thackery” che li scoprì nel 1950.
Sono i resti di una grande nebulosa oscura erosa dalla radiazione UV, ciuffi densi di gas e polveri, con diametro di quasi 1,4 anni luce, conosciuti anche come “globuli di Bok”, dall’astronomo Bart Bok, che li osservò nel 1947 in altre strutture dell’universo.

NGC 7023: The Iris Nebula
Welcome To Space & The Night Sky Community
These clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of theconstellation Cepheus. Sometimes called the Iris Nebula, NGC 7023 is not the only nebula in the sky to evoke the imagery of flowers, though. Still, this deep telescopic view shows off the Iris Nebula's range of colors and symmetries in impressive detail.Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the dusty clouds glow with a faint reddish photoluminesence as some dust grainseffectively convert the star's invisibleultraviolet radiation to visible red light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years.

Math is so much cooler today with computer animation.
