The expansive, 600 trillion km wide Rosette Nebula, 5,000 light years away from home. 💫 🌌 🔭 My 2nd Page @TheOurDeepSpace Our YouTube Channel. Link in Bio @TheOurSpace
The lovely, symmetric shape of this stellar nursery is sculpted by the winds and radiation from its central cluster of hot young, O-type stars. Stars in the energetic cluster, cataloged as NGC 2244, are only a few million years young, while the central cavity in the Rosette Nebula, is about 50 light-years in diameter. The nebula can be seen with a small telescope toward the constellation of Monoceros, the Unicorn. 🌌
The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses. 🌌
Do you love Rosette Nebula ❤

💫 Astronomers are convinced they've found two new Earth-like planets in our galaxy, and both appear so similar to our own, they're now among the top 19 known exoplanets with potentially habitable environments.
Orbiting a neighbouring star in the constellation of Aries just 12.5 light years away, one of these two planets might in fact hold the greatest similarity to Earth we've discovered so far. "The two planets resemble the inner planets of our Solar System," explains lead author Mathias Zechmeister, an astrophysicist at the University of Göttingen. "They are only slightly heavier than Earth and are located in the so-called habitable zone, where water can be present in liquid form." Despite its proximity, this nearby Teegarden's star was only discovered back in 2003. About ten times lighter than our own Sun and one of the smallest stars we know of, the old red dwarf, which is roughly 8 billion years old, has proved a challenge to research.
According to the team, other planetary systems around similar stars have always been detected using the transit method, when an orbiting planet passes in front of a star, blocking Earth's view and causing the bright celestial object to darken for a brief moment.
