RAS Warns of Potential Danger of Starlink Satellites To Ground-Based Astronomy

The Royal Astronomical Society has issued a publication stating their concern about the potential negative impact of the SpaceX starlink sattelites that was launched some days back on star gazing and ground-based astronomy. The Starlink and other similar networks have an aim of developing a low-cost, high-performance satellite bus and requisite customer ground transceivers to…

Atomic Nucleus

The basic particles of an atom are the proton, neutron and electron. One model of an atom pictures a dense positively charged nucleus. A cloud of negative electricity surrounds it. The cloud is produced by electrons orbiting around the nucleus. The nucleus contains neutrons and positively charged protons. A nucleus is only a tiny fraction…

Cyclotron

A Cyclotron is a kind of atom smasher. It has been used to split the atoms of most elements. It is a machine which produces high speed beam of atomic particles. The beam contains protons, heavy hydrogen nuclei, our alpha particles. By firing high speed particles into the atom’s nucleus, scientist cause the nucleus to…

Asteroids may be harder to break

A Johns Hopkins study discovered that asteroids my be stronger than previously thought. The study carried out using a new understanding of rock feature and computer modelling method to simulate asteroid collisions. The findings will be published on March 15 on Icarus. “We used to believe that the larger the object, the more easily it…

Tilted Exoplanets may explain astronomical mysteries

When a exoplanet tilts to its side with respect to its star, it is called planet obliquity, this is responsible for the change in season we experience on Earth where a part is tilted towards the Sun at some specific times leading to the tilted part experiencing a harsh sunlight and the other side left…

New Horizons data points to Large Kuiper Belt Objects

The vital data sent by The New Horizons spacecraft when it performed its Pluto flyby in July 2015 has pointed to the scarcity of small objects below a mile in diameter in the Kuiper Belt. Pluto and its largest moon Charon are far too distant from Earth to be completely studied by a telescope so…
