The best time to see the Milky Way is up to a week before and within days after a new moon to avoid excess light in the night sky. Through the remainder of this summer into early fall, a new moon ...
The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [ 7][ 8][ 9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
According to LiveScience, the best times this summer to see the Milky Way are through July 8, July 28 through Aug. 7 and Aug. 26 through Sept. 6. Ian Hewitt, president of the Grand Strand ...
The Great Attractor is a region of gravitational attraction in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster of galaxies that includes the Milky Way galaxy, as well as about 100,000 other galaxies. The observed attraction suggests a localized concentration of mass having the order of 10 16 solar ...
When viewing space from Earth, the attenuation, interstellar dust and stars in the plane of the Milky Way (the galactic plane) obstruct the view of around 20% of the extragalactic sky at visible wavelengths. As a result, optical galaxy catalogues are usually incomplete close to the galactic plane.
There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years) of the Milky Way, [ 2 ] but not all of them are necessarily in orbit, and some may themselves be in orbit of other satellite galaxies. The only ones visible to the naked eye are the Large and Small Magellanic Clouds, which have been observed since ...
In astrobiology and planetary astrophysics, the galactic habitable zone is the region of a galaxy in which life might most likely develop. The concept of a galactic habitable zone analyzes various factors, such as metallicity (the presence of elements heavier than hydrogen and helium) and the rate and density of major catastrophes such as supernovae, and uses these to calculate which regions ...
An asteroid will whiz harmlessly past Earth this weekend. With the right equipment and timing, you just might spot it. Called 2024 MK, the space rock will make its closest approach to Earth ...
