The existence of dark matter remains one of the greatest mysteries of the universe. While studies have indirectly hinted at its existence, its invisible nature makes this elusive substance very difficult to detect, thus its ...
Primordial black holes (PBHs) are fascinating cosmic bodies that have been widely investigated by astrophysicists worldwide. As suggested by their name, these are black holes believed to have appeared in the universe's early ...
If, as astronomers believe, the deaths of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible.

An international team of astronomers reports the detection of a new sub-Jupiter-mass alien world orbiting an M-dwarf star. The newly found exoplanet, designated OGLE-2014-BLG-0319Lb, turns out to be about half as massive ...
Tantalizing evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star. The results include four new discoveries that are consistent ...

Using the microlensing technique, an international team of astronomers has detected a new distant alien world. The newly found exoplanet, designated OGLE-2018-BLG-0799Lb, is about five times less massive than Jupiter and ...
An upcoming NASA mission could find that there are more rogue planets—planets that float in space without orbiting a sun—than there are stars in the Milky Way, a new study theorizes.

Using gravitational microlensing technique, an international group of astronomers has found a new substellar system whose composition remains a puzzle. The newly detected system, designated MOA-2015-BLG-337L, may consists ...
Using microlensing method, an international team of astronomers has detected a new "super-Earth" alien world circling a low-mass star about five times less massive than our sun. The finding is detailed in a paper published ...
