Sep 27, 2024 · The elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole and a family of roughly 15,000 globular star clusters. For comparison, our Milky Way galaxy contains only a few hundred billion stars and about 150 globular clusters.

After years of analysis, Kepler discovered that Mars's orbit was likely to be an ellipse, with the Sun at one of the ellipse's focal points. This, in turn, led to Kepler's discovery that all planets orbit the Sun in elliptical orbits, with the Sun at one of the two focal points.

Apr 17, 2023 · M87 is a giant elliptical galaxy that formed from the collision of other galaxies. It’s 10 times the size of our Milky Way galaxy. To find the 3D shape of the galactic blob that looks...

NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.

Oct 22, 2024 · Elliptical galaxies have shapes that range from completely round to oval. They are less common than spiral galaxies. Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or structure.

TOI-2580 b is a gas giant exoplanet that orbits a F-type star. Its mass is 0.63 Jupiters, it takes 3.4…

Elliptical galaxies are characterized by several properties that make them distinct from other classes of galaxy. They are spherical or ovoid masses of stars, starved of star-making gases.

Mars is no place for the faint-hearted. It’s dry, rocky, and bitter cold. The fourth planet from the Sun, Mars is one of Earth's two closest planetary neighbors (Venus is the other). Mars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light.

Nov 16, 2015 · The supergiant elliptical galaxy M87, with its jet. Astronomers have measured distinct pulsations from this galaxy, the slowly flickering light of its pulsating stars.

Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass, resulting in about 38% of Earth's surface gravity. Mars is the only presently known example of a desert planet, a rocky planet with a surface akin to that of Earth's hot deserts.
