A new record for the number of people in space at the same time, though not necessarily all in orbit, was reached on 25 May 2023. 20 people were in space simultaneously, with eleven people aboard the ISS, three on Tiangong, and six on VSS Unity. [10]
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 ...

Initial magnitude at discovery was 14.9. [2] After discovery, the Zwicky Transient Facility project found a precovery image of the supernova at magnitude 15.87 two days before discovery. [ 9 ] The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole , based on current ...
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
