Correcting historic sea surface temperature measurementsWhy did the oceans warm and cool at such different rates in the early 20th century? New research points to an answer both as mundane as a decimal point truncation and as complicated as global politics. Part history, part climate science, this research corrects decades of data and suggests that ocean warming occurred in a much more homogenous way.Supernova observation first of its kind using NASA satelliteResearchers have published findings about a supernova observed using TESS, adding new insights to long-held theories about the elements left behind after a white dwarf star explodes into a supernova.Vast majority of dietary supplements don't improve heart health or put off death, study findsIn a massive new analysis of findings from 277 clinical trials using 24 different interventions, researchers say they have found that almost all vitamin, mineral and other nutrient supplements or diets cannot be linked to longer life or protection from heart disease.Joshua trees facing extinctionThey outlived mammoths and saber-toothed tigers. But without dramatic action to reduce climate change, new research shows Joshua trees won't survive much past this century.A material way to make Mars habitableNew research suggests that regions of the Martian surface could be made habitable with a material -- silica aerogel -- that mimics Earth's atmospheric greenhouse effect. Through modeling and experiments, the researchers show that a 2- to 3-centimeter-thick shield of silica aerogel could transmit enough visible light for photosynthesis, block hazardous ultraviolet radiation, and raise temperatures underneath permanently above the melting point of water, all without the need for any internal heat source.Out of Africa and into an archaic human melting potGenetic analysis has revealed that the ancestors of modern humans interbred with at least five different archaic human groups as they moved out of Africa and across Eurasia.Strange new species of duck-billed dinosaur identifiedThe most complete skull of a duck-billed dinosaur from Big Bend National Park, Texas, is revealed in a new article as a new genus and species, Aquilarhinus palimentus. This dinosaur has been named for its aquiline nose and wide lower jaw, shaped like two trowels laid side by side.Small horned dinosaur from China, a Triceratops relative, walked on two feetAuroraceratops, a bipedal dinosaur that lived roughly 115 million years ago, has been newly described by paleontologists. More than 80 individuals of this species have been found in China's Gansu Province.

Angelic halo orbit chosen for humankind’s first lunar outpost
Mission planners at NASA and ESA’s Operations Centre (ESOC) have spent months debating the pros and cons of different orbits, and have now decided on the path of the lunar Gateway.Powering the future with lunar soil
Building a lunar base would be one of the next logical steps in our exploration of the Solar System, but the survival of a future crew depends on access to a reliable source of energy. An ESA Discovery & Preparation study explored how lunar regolith – the dust, soil and rock on the Moon's surface – could be used to store heat and provide electricity for future astronauts, rovers and landers.Building a toolkit for the Moon
As the world celebrates 50 years since the first lunar landing, the team at ESA’s astronaut centre is looking to the future of lunar exploration. This includes developing prototypes for rock and soil sampling equipment to be used on the Moon.Third European service module for Orion to ferry astronauts on Moon landing
NASA and ESA have a long term plan for Europe to deliver the European Service Modules for Orion. With NASA’s announcement to bring humans back to the lunar surface before the end of 2024, it was also decided that the third ESA-provided European Service Module will contribute to this mission.ESA confirms asteroid will miss Earth in 2019
Asteroid 2006 QV89, a small object 20 to 50 metres in diameter, was in the news lately because of a very small, 1-in-7000 chance of impact with Earth on 9 September 2019.Gaia starts mapping our galaxy’s bar
The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from ESA’s Gaia mission with complementary observations from ground- and space-based telescopes.ESA identifies demand for satellites around the Moon
Dozens of very different commercial and institutional missions to the Moon are planned for the coming decades.
These encompass everything from NASA’s manned Lunar Gateway research station and cubesats from start-ups and universities to commercial landers carrying rovers.
The heightened interest in going to the Moon shows that there could be a market in providing satellite communications beyond Earth.To the Moon – down south
Half a century ago humans stepped on the Moon for the first time in a set of sorties that awed the world. Over the years since we have explored our Solar System with robotic scouts and established a permanent human presence in space with the International Space Station.
