The Milky Way galaxy is just one of the billions of galaxies in the universe.
The universe is a vast expanse of space that contains all of everything in existence. It contains all of the galaxies, stars, and planets. The exact size of the universe is unknown but the scientists believe the universe is still expanding outward.]]> 2022-10-21 13:10:41 UTC https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2350679300 GraciellaM https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2350758687 Stephenson 2:18 is currently known as the biggest star of all time, including the fact that our star is nothing compared to this red supergiant!

When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion we call a supernova.]]> 2022-10-21 14:09:22 UTC https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2350770734 GraciellaM https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2350782263  The Orion constellation is one of the most obvious and recognizable constellations in the sky,  The Orion constellation has 3 Brightest stars, The brightest of them all is Rigel, then Betelguese, and lastly Bellatrix.]]> 2022-10-21 14:16:42 UTC https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2350782263 ariaokay https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2351364453 The Cartwheel Galaxy is a lenticular ring galaxy about 500 million light-years away in the constellation Sculptor. It has a D₂₅ isophotal diameter of 44.23 kiloparsecs, and a mass of about 2.9–4.8 × 10⁹ solar masses; its outer ring has a circular velocity of 217 km/s.

Unlike modern stars, which are powered by nuclear fusion in their cores, a quasi-star's energy would come from material falling into a black hole at its core]]> 2022-10-22 02:06:21 UTC https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2351379232 margarette_ https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2351489381 The Large Magellanic Cloud (LMC) is the southern sky’s greatest celestial wonder. It is the Milky Way’s biggest satellite galaxy, just 160,000 light-years distant, The LMC is an easy naked-eye object even from mildly light-polluted areas,  It  lies primarily in the far-southern constellation Dorado the Swordfish, but some of it spills over into the neighboring constellation Mensa the Table Mountain, which lies even farther south.]]> 2022-10-22 07:59:31 UTC https://padlet.com/GraciellaM/pzpggoc3spnvd96y/wish/2351489381
