For decades, astronomers and astrophysicists have been looking at methods of detecting dark matter, the stuff believed to make up about a quarter of the Universe. Its existence was hypothesized a long time ago, but no practical experiments were able to show it exists. This has frustrated many experts, while others be... |

For more than 70 years, dark matter has been the holy grail for astronomers and astrophysicists. Discovering it would allow the scientists to finally determine whether their theories on how the Universe appeared, and currently expands, are correct, or if they need to start everything from scratch. Similar to how hist... |

Astronomers have known for a long time that some of the smaller asteroids flying through space are not actually pieces of rock, but loosely-bound piles of rubble and debris. According to the basic laws of physics, these components should not stick together, but fly apart. However, this is not the case, and scientists... |

As many of you already know, the Earth's atmosphere is in fact a very powerful anti-asteroid shield. Theoretically, tens of meteorites and other similar objects should impact the ground each day, but their vast majority burns up high above the planet, on account of the friction force it generates when it enters ... |

One of the most used methods of analyzing the distribution of dark matter throughout the Universe is called weak gravitational lensing (WGL). At this point, our technology has not yet evolved to a point where we can observe the elusive stuff directly, so we must rely on indirect observations to assess some of its mos... |

As the story goes, Sir Isaac Newton (born on January 4th, 1643) was inspired to formulate his theory of gravitation by an apple falling on his head as he was taking a walk in a garden. It was later revealed that the fruit didn’t touch the scientist at all. However, in its turn, the altered story inspired many, ... |
