Interstellar object, an object that has entered the solar system from interstellar space. As of 2023, two such objects have been observed: ‘Oumuamua, which was discovered in 2017, and Comet Borisov, which was discovered in 2019. ‘Oumuamua was discovere

The scientific goals include the study of the Heliopause and of the interstellar medium, astrometry with a very long baseline, the study of the gravitational lensing effect of the Sun and the encounter with some Kuiper belt object. Such missions involve technological achievements like the testing ...

The maps and an accompanying journal article appear in the Aug. 15 issue of the journalScience. The researchers say their work demonstrates a new way of uncovering the location and eventually the composition of theinterstellar medium—the material found in the vast expanse between star systems with...

The first meter-scale interstellar meteor (IM1) was detected by US government sensors in 2014, identified as an interstellar object candidate in 2019, and confirmed by the Department of Defense (DoD) in 2022. We use data from a nearby seismometer to localize the fireball to a ∼16km216km...
While the Local Group contains several dIrr galaxies, BCDs are rarer and only a single such object, IC 10, has been suggested to be located within its volume [21]. Green peas are even rarer than BCDs and are therefore commonly observed at redshifts z > 0.1. Not surprisingly, dIrrs ...
