Black hole Compact astrophysical object with gravity so strong nothing can escape

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

The litre or liter is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metre (m3). A cubic decimetre occupies a volume of 10 cm × 10 cm × 10 cm and is thus equal to one-thousandth of a cubic metre.

Oort cloud Theoretical cloud of planetesimals at the far edge of the solar system

The Oort cloud, sometimes called the Öpik–Oort cloud, first described in 1950 by Dutch astronomer Jan Oort, is a theoretical cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 au. It is divided into two regions: a disc-shaped inner Oort cloud and a spherical outer Oort cloud. Both regions lie beyond the heliosphere and in interstellar space. The Kuiper belt and the scattered disc, the other two reservoirs of trans-Neptunian objects, are less than one thousandth as far from the Sun as the Oort cloud.

Solar System The planets and their moons that orbit around the Sun

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the moons—two are larger than the smallest planet, Mercury.

Lion large cat native to Africa and Asia

The lion is a species in the family Felidae and a member of the genus Panthera. It has a muscular, deep-chested body, short, rounded head, round ears, and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions have a prominent mane. With a typical head-to-body length of 184–208 cm (72–82 in) they are larger than females at 160–184 cm (63–72 in). It is a social species, forming groups called prides. A lion pride consists of a few adult males, related females and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, the species typically does not.

Milky Way Spiral galaxy containing our Solar System

The Milky Way is the galaxy that contains our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος. From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies.

COVID-19 pandemic in France Ongoing COVID-19 viral pandemic in France

The COVID-19 pandemic in France is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached France on 24 January 2020, when the first COVID-19 case in both Europe and France was identified in Bordeaux. The first five confirmed cases were all individuals who had recently arrived from China. A Chinese tourist who was admitted to hospital in Paris on 28 January died on 14 February, making it the first COVID-19 death in France as well as the first COVID-19 death outside Asia. A key event in the spread of the disease across metropolitan France as well as its overseas territories was the annual assembly of the Christian Open Door Church between 17 and 24 February in Mulhouse which was attended by about 2,500 people, at least half of whom are believed to have contracted the virus. On 4 May, retroactive testing of samples in one French hospital showed that a patient was probably already infected with the virus on 27 December, almost a month before the first officially confirmed case.
