Hubble announces discovery of other galaxies, December 30, 1924Jessica MacNeil
Nashville, Tennessee, nicknamed “Music City,” is both the epicenter of country music and the home of many other genres – indie and southern rock, rap, R&B, blues, electronic and jazz. It’s the perfect place to begin a journey through American music. The I-40, known as the “...
B. The galaxies. C. The signatures. D. The astronomers.24. What do we know about the massive star? D A. It was once clearly observed. B. It experienced a temporary change. C. It could only be traced with the VLT. D. It evidently existed in the distant galaxy.25. Which of the ...
If the supernova explosion is stronger on one side, it can kick the pulsar entirely out of the supernova remnant (some astronomers call this “getting a birth kick”). We know such kicks happen because we see a number of young supernova remnants in nearby galaxies where the pulsar is to...
of its member galaxies, the luminosity of the extended X-ray emission, and the high stellar mass content all point to a collapsed dark matter halo with total mass 10^14 M⊙, making it the most distant X-ray detected...
When LRDs were first discovered, some suggested that cosmology was “broken.” If all of the light coming from these objects was from stars, it implied that some galaxies had grown so big, so fast, that theories could not account for them. ...
Still unknown, the scientists said, is whether the massive black holes initially began as the remnants of extremely massive early stars or some other scenario of collapsing mass. “Getting a good census of dwarf galaxies with massive black holes is an important first step to resolving this questi...
It was during the latter part of this that he discovered Uranus. Afterwards, supported by the royal grant in recognition of his work, he was able to devote himself entirely to astronomy. His final achievements spread from the sun and moon to remote galaxies (of which he discovered hundreds)...
