NGC 602c is a looser grouping 11 arc-minutes to the NE, which includes the WO star AB8. [9] NGC 602 includes many young O and B stars and young stellar objects, with few evolved stars. [10] Ionisation in the nebula is dominated by Sk 183, an extremely hot O3 main sequence star visible as the bright isolated star at the centre of the Hubble ...
Here's a look inside NASA's plan to launch an "artificial star" over the U.S. before the end of the decade. A rendering provides a visual of how a ground observatory may communicate with an ...
Artist's conception of a white dwarf, right, accreting hydrogen from the Roche lobe of its larger companion star A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
This list of exoplanets discovered in 2023 is a list of confirmed exoplanets that were first reported in 2023. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. Name Mass (M J) Radius (R J) Period (days) Semi-major axis (AU) Temp. (K) Discovery method Distance (ly) Host star mass (M ☉) Host star temp. (K ...
So, NASA—along with George Mason University and the National Institute of Standards and Technology—is going to place an artificial star into geostationary orbit to help improve astronomical ...
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
KOI-4878.01 is an exoplanet candidate that orbits the F-type main-sequence star KOI-4878.It is located about 1075 light years (329 parsecs) from Earth. [1] [2] [3] The features of the planet are very similar to that of Earth, and if it is confirmed, it would be one of the most Earth-like planets found. [4]
In 2024, two older and more distant galaxies, JADES-GS-z14-0 and JADES-GS-z14-1, were found. [ 6 ] JADES-GS-z13-0 is located in the Great Observatories Origins Deep Survey – South (GOODS-S) field in the constellation Fornax , which includes the Hubble Ultra Deep Field .
