There are approximately 1.25 million identified animal species, but there could be up to 30 million unidentified insect species and 1 million mite species. The number of animal species on Earth is declining due to human-caused events such as the Holocene Extinction Event. There are approximately 1,250,000 identified animal species. This includes 1,190,200 invertebrates, including […]
Plants include 375,000 species, with 297,326 identified, and are photosynthetic with chloroplasts. They consist of green algae and terrestrial plants, with vascular plants being the most dominant and bryophytes being less advanced. Seeds allowed plants to colonize drier areas, and flowering plants evolved to involve mobile animals in pollination. There are an estimated 375,000 plant […]
Estimating the number of bacterial species is impossible with current technology. Using DNA reassociation and mathematical models, estimates range from 10 million to 1 billion species. Sequencing fragments is more cost-effective than whole genomes, and one survey found 20,000 species in 1 quart of seawater. Estimating the exact number of species of bacteria is impossible […]

NASA warns of 4,700 potentially hazardous asteroids (PHAs) in Earth’s solar system that could cause serious damage if they collide with the planet. Only 20-30% of PHAs have been located. No one has been killed by an impact event, but PHAs could jeopardize space missions. According to the US National Aeronautics and Space Administration (NASA), […]
Astronomers have found that the star Kepler 11145123 is the closest to a perfectly round sphere ever measured, using NASA’s Kepler telescope and asteroseismology. The star is 5,000 light-years away and has a diameter of 1.86 million miles. It is named after 17th-century astronomer Johannes Kepler. Astronomers from the Max Planck Institute for Solar System […]
Tunnel systems require the work of geologists, surveyors, civil engineers, metallurgists, masons, and construction crews. They ensure safety, reliability, and maintenance. Private companies are often contracted for specialized work. Professionals take measurements, design structures, and construct roads and railways. Cooperation is key. Dozens of different professionals are involved in the design, construction and maintenance of […]
WISE telescope discovered 2.5 million active black holes, some up to 10 billion light-years from Earth. Most stars won’t become black holes, and there’s no standardized naming system. M87 is the largest known black hole. Astronomers have discovered about 2.5 million active black holes using the Wide-field Infrared Survey Explorer (WISE) telescope. Some of these […]
Illegal substances, also known as illegal drugs, are banned due to their potential for abuse and fall into three categories: depressants, stimulants, and hallucinogens. Controlled substances can also be illegal if used or distributed incorrectly. The use and possession of illegal substances are punishable by law, and the punishment varies depending on the jurisdiction and […]
Chemical elements are types of atoms, with 118 observed and 98 occurring naturally on Earth. 20 are created artificially. Elements come from supernova, stellar, and Big Bang nucleosynthesis. The first stars formed 300 million years after the Big Bang, initiating stellar nucleosynthesis. Supernova nucleosynthesis creates elements heavier than iron. A chemical element is a type […]
