Microlensing is a powerful astronomical technique used to detect exoplanets—planets that orbit stars outside our solar system. This method relies on the gravitational lensing effect, where the ...

South Africa has taken one giant leap into exoplanet discovery capabilities and astronomical research with the launch of the ...

“We [will be able to] move quickly and map out very large areas of the sky,” adds Josh Schlieder, the telescope’s wide-field ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our Sun," according to NASA/ESA. Credit: NASA, ESA, P. McGill (Univ.

The team behind this research reached this conclusion by studying 20 extrasolar planets or "exoplanets" as they crossed, or "transited," the faces of their parent stars using the Hubble Space ...

That’s a technique called gravitational lensing and researchers have used it for decades to make astonishing ... But scientists have found planets way beyond our own solar system. Known as exoplanets, ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of spacetime called gravitational waves, first proposed by Albert Einstein ...

Neutron stars may have analogous features. According to new research, these neutron-star mountains could produce detectable oscillations of space and time known as gravitational waves. Neutron stars ...

The examination of parity symmetry in gravitational interactions has drawn increasing attention. Although Einstein’s General Relativity is parity-conserved, numerous theories of parity-violating (PV) ...
