The mass of the nebula is estimated at about 0.6 solar masses, while the progenitor star was likely about 2.3 times the mass of the Sun. [4] NGC 2818 presents a complex morphology, and overall has bipolar structure, making it a bipolar nebula. The two lobes are somewhat broken and irregular.
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.
Simulated collision of two neutron stars. A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
The pulsar in the Crab Nebula is travelling at 375 km/s relative to the nebula. [ 165 ] A long-standing puzzle surrounding type II supernovae is why the remaining compact object receives a large velocity away from the epicentre; [ 166 ] pulsars , and thus neutron stars, are observed to have high peculiar velocities , and black holes presumably ...
Has been named the “Heart nebula” because of its resemblance to a human heart. Henize 70 (N70 or DEM L301) [47] 300 ly (92 pc) [48] H II region: The N 70 Nebula, in the Large Magellanic Cloud has a shell structure and is really a bubble in space. It is a "Super Bubble". Barnard's Loop: 300 ly (92 pc) [49] [50] H II region
The Mice Galaxies NGC 4676. A galactic tide is a tidal force experienced by objects subject to the gravitational field of a galaxy such as the Milky Way.Particular areas of interest concerning galactic tides include galactic collisions, the disruption of dwarf or satellite galaxies, and the Milky Way's tidal effect on the Oort cloud of the Solar System.
The hotly anticipated Xbox exclusive space exploration game from Bethesda got a huge, in-depth showcase over the weekend Starfield: Everything you need to know about Bethesda’s Xbox exclusive ...
When two spiral galaxies collide, the hydrogen present on their disks is compressed, producing strong star formation as can be seen on interacting systems like the Antennae Galaxies. In the case of the Andromeda–Milky Way collision, it is believed that there will be little gas remaining in the disks of both galaxies, so the mentioned ...
