The Mysterious Dark Matter
Dark Matter- image by Sciencealert Did you know that we know less about the universe than we do about what we don’t know? It’s true! Dark energy is one of the biggest mysteries out there. We know it’s responsible for about 68% of the universe’s expansion, but we have no idea what it is or […] Continue reading
Dark Matter
In studies of galaxies and star clusters, astronomers have found that many of these bodies appear to move in ways that don’t reflect the amount of visible matter in the system. For instance, some galaxies appear to orbit much faster than they should be based on the amount of stuff we can see within them. […] Continue reading
Primordial Stars and Dark Matter
A little over a month ago, astronomers in Western Australia detected the signals of stars that formed within the earliest epoch of the Universe. This discovery marks the detection of the oldest signals ever to be received, and with it, evidence for the presence of dark matter at a time when the lights of the … Continue reading Primordial Stars and Dark Matter → Continue reading

The Unseen
The visible universe-including galaxies,stars and planets only make up 4 percents of the universe (REALLYYYY). What about another 96 percents of it? In reality, another 96 percents consists of the thing that is unseen. Besides, we can’t really identify or perhaps understand what that 96 percents is made up of. From the perspective of the scientists, … Continue reading The Unseen Continue reading
Dark matter
Dark matter is a hypothetical matter that neither emits nor absorbs light or any other electromagnetic radiations so that it cannot be seen with any telescopes nowadays. However, dark matter accounts for most of the matter in the universe, and it should be responsible for many phenomena occurring in the universe. According to the standard… Continue reading
80% of the Universe That We Can’t See
Image Source Over the past couple of centuries, we have learned a great deal about our Universe. However, the more we seem to learn about the cosmos, the more we realize that we do not understand. When Jan Oort and Fritz Zwicky first hypothesized the existence of dark matter in our Universe, a breakthrough in […] Continue reading

Dark Matter Discovered?
Scientists announced today that they may have finally found dark matter. Dark matter is the invisible matter making up most of the universe, but scientists can’t see it because it emits no light. Scientists only know it exists because dark matter’s gravity bends light – gravitational lensing – and because stars are orbiting in galaxies […] Continue reading
