List of years in science (table)
+...

A number of significant scientific events have occurred or are scheduled to occur in 2019.

Events

January

1 January: The New Horizons space probe flies by Ultima Thule, a remote Kuiper belt object.[1][2][3]
17 January: Australopithecus sediba found to be distinct from, but similar to, both the older Australopithecus africanus and the younger Homo habilis.[17]
23 January: Five identical cloned gene-edited monkeys (similar to the one pictured above) created, in order to study several medical diseases.[31][32][33]
  • 24 January
    • NASA announces that the Opportunity rover has been on the planet Mars for 15 years.[35][36]
    • NASA scientists report the discovery of the oldest known Earth rock – on the Moon. Apollo 14 astronauts returned several rocks from the Moon and later, scientists determined that a fragment from one of the rocks contained "a bit of Earth from about 4 billion years ago." The rock fragment contained quartz, feldspar, and zircon, all common on the Earth, but highly uncommon on the Moon.[37]
    • The complete axolotl genome is reported to have been sequenced by the University of Kentucky.[38][39]
  • 25 January – AlphaStar, a new artificial intelligence algorithim by Alphabet's DeepMind subsidiary, defeats professional players of the real-time strategy game StarCraft II in ten rounds out of eleven.[40][41][42]
  • 29 January – Researchers at Purdue University's College of Engineering release a paper in the jouranl ACS Sustainable Chemistry & Engineering detailing a new process to turn plastic waste in hydrocarbonic fuels.[43][44][45]
  • 30 January – Scientists report that several types of humans, including Denisovans, Neanderthals and related hybrids, may have habitated the Denisova Cave in Siberia over thousands of years, but it is unclear whether they ever shared the cave.[46]
  • 31 January
    • Researchers at the University of California, Berkeley, demonstrate a new form of 3D printer, which uses light exposure to transform a viscous liquid into complex solid objects.[47]
    • A new AI developed by RMIT University in Melbourne and trained to play the 1980s video game Montezuma’s Revenge is reported to be 10 times faster than Google DeepMind and able to finish the game.[48]

February

3 February: Medical scientists announce that iridium (image above) attached to albumin produces a photosensitized molecule able to penetrate and, via photodynamic therapy, destroy cancer cells.[49][50]

Predicted and scheduled events

April

May

June

  • June – the first crewed flight into orbit by a private company (SpaceX) [66]

July

October

  • The CHEOPS space telescope, whose mission is to study the formation of extra-solar planets, is expected to launch in October or November.[67]

November

  • 11 November – a rare transit of Mercury will occur.
  • November - NASA's contract with the Russian space agency expires.[68]

December
