  Antimatter is the same as ordinary matter    except that it has the opposite electric charge .  For instance, an electron, which has a negative charge, has an antimatter partner known as a positron. A positron is a particle with the same mass as an electron but a positive charge.  Particles with no electric charge, like neutrons, are often their own antimatter partners. But researchers have yet to determine if mysterious tiny particles known as neutrinos , which are also neutral, are their own antiparticles. Although it may sound like something out of science fiction, antimatter is real. Antimatter was created along with matter after the Big Bang . But antimatter is rare in today's universe, and scientists aren't sure why. Humans have created antimatter particles using ultra-high-speed collisions at huge particle accelerators such as the Large Hardon collider,  which is located outside Geneva and operated by CERN (the European Organization for N...

  First meteor shower of 2022 The Quadrantids meteor shower peaks on January 3rd night and early January 4th morning. Depending on light, this New Year's shower is reported to generate brighter-than-average shooting stars, with 25 to 100 visible meteors per hour. Venus , Mars and Saturn triangle  In the next upcoming weeks, Venus, Mars, and Saturn will be gathered together in a tight triangular grouping. The planets will create a triangular shape with changing angles until April 1, when they will appear in a linear fashion. Saturn will join Mars in early April, and the two will appear directly beside one other between April 3 and 5. On April 4, the two planets will be nearest together, separated by only half a degree of arc, roughly equivalent to the diameter of the full moon. Partial Solar eclipse In 2022 (April 30), there will be two partial solar eclipses, which happen when the moon covers part of the sun disc in the sky. The first will be visible over parts of the Pac...

  The   expansion of the universe   is the increase in  distance    between any two given gravitationally unbound    parts of the  observable universe    with time.   It is an  intrinsic    expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it. This expansion involves neither space nor objects in space "moving" in a traditional sense, but rather it is the metric (which governs the size and geometry of spacetime itself) that changes in scale. As the spatial part of the universe's  space time matric    increases in scale, objects become more distant from one another at ever-increasing speeds. To any observer in the universe, it appears that all of space is expanding, and that all but  the nearest galaxies    (which are bound by gravity) recede at  speeds that are proportional to their dist...
