Is the Lagoon Nebula a Messier object? Is the Hubble Telescope in our solar system? Do Oort cloud objects orbit the sun? Does every solar system have an Oort cloud? Is the Oort cloud part of our solar system? Do Kuiper belt objects orbit the sun? Is the Andromeda galaxy the brightest ...
It's possible that the sun is even larger than previously thought. Xavier Jubier, an engineer and solar eclipse researcher, creates detailed models of solar andlunar eclipsesto determine precisely where the moon's shadow would fall during thesolar eclipse. But when he matched actual photos and h...
Which planet is bigger: Earth or Venus? What is the sun's mass? Is Venus the brightest planet? What is the transit of Venus? What is another name for the planet Venus? What is the mass of planetary nebula? Is Venus a star or a planet?
More than half of the moon's face appears to be getting sunlight. Full moon: The moon is 180 degrees away from the sun and is as close as it can be to being fully illuminated by the sun from our perspective. The sun, Earth and the moon are aligned, but because the moon’s orbit...

“VY Canis Majoris is behaving a lot like Betelgeuse on steroids,” explained the study’s leader, astrophysicist Roberta Humphreys of the University of Minnesota, Minneapolis. This Hubble Space Telescope image shows the huge nebula of material cast off by the hypergiant star VY Ca...
