What's that at the end of the road? The Sun. Many towns have roads that run east-west, and on two days each year, the Sun rises and sets right down the middle. Yesterday, in some parts of the world (today in others), is one of those days: an equinox. Not only is this a day of equal night and day time, but also a day when the sun rises precisely to the east and sets due west. Displayed here is a picturesque rural road in Alberta, Canada that runs approximately east-west. The featured image was taken during the September Equinox of 2021, but the geometry remains the same every year. In many cultures, this March equinox is taken to be the first day of a season, typically spring in Earth's northern hemisphere, and autumn in the south.

Made with narrowband filters, this cosmic snapshot covers a field of view about the size of the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized sulfur, hydrogen, and oxygen gas.
Embedded in the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 50 light-years across.
Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernovae enrich the interstellar material with heavy elements to be incorporated in future generations of stars.

İzlanda Üzerinde Ejderha Aurorası
Günün Astronomi Görseli 14 Ocak 2024 Görsel & Telif: Jingyi Zhang & Wang Zheng Daha önce gökyüzünde bir ejderha gördünüz mü? Gerçekte uçan ejderhalar var olmasalar da 2019’da, İzlanda’nın göklerinde şekli dev bir ejderhaya benzeyen bir aurora oluştu.  Aurora Güneş’in koronasındaki, Dünya’nın manyetosferine doğru değişen bir gezegenlerarası manyetik alanı izleyen, bir güneş rüzgarına yüklü…

From NASA (Astronomy Picture of the Day - March 11, 2024)
What glows in the night? This night featured a combination of usual and unusual glows. Perhaps the most usual glow was from the Moon, a potentially familiar object. The full Moon's nearly vertical descent results from the observer being near Earth's equator. As the Moon sets, air and aerosols in Earth's atmosphere preferentially scatter out blue light, making the Sun-reflecting satellite appear reddish when near the horizon. Perhaps the most unusual glow was from the bioluminescent plankton, likely less familiar objects. These microscopic creatures glow blue, it is thought, primarily to surprise and deter predators. In this case, the glow was caused primarily by plankton-containing waves crashing onto the beach. The image was taken on Soneva Fushi Island, Maldives just over one year ago.

SPACEMAS DAY 9 ✨🪐🌎☄️☀️🌕
Driven by powerful stellar winds, the expanding gas and dust frame the hot, luminous star Wolf-Rayet 124 in this sharp infrared view. The 6-spike star pattern is characteristic, taken with the 18 hexagonal mirrors of the James Webb Space Telescope. About 15,000 light-years away toward the pointed northern constellation Sagittarius, WR 124 has over 30 times the mass of the Sun. Produced in a brief and rarely spotted phase of massive star evolution in the Milky Way, this star's turbulent nebula is nearly 6 light-years across. WR 124's impending stellar death will be a supernova explosion and any dusty interstellar debris that survives the supernova will influence the formation of future generations of stars.
