Did Earth's early rise in oxygen help multicellular life evolve
Write a comment
Atlanta GA (SPX) May 19, 2021
Scientists have long thought that there was a direct connection between the rise in atmospheric oxygen, which started with the Great Oxygenation Event 2.5 billion years ago, and the rise of large, complex multicellular organisms.
That theory, the "Oxygen Control Hypothesis," suggests that the size of these early multicellular organisms was limited by the depth to which oxygen could diffuse

China postpones launch of rocket carrying space station supplies
Write a comment
China has postponed the planned launch Thursday of a rocket carrying supplies for its new space station due to technical reasons, state media said.
The China Manned Space Agency gave no details on what the reasons were, and said only that a new launch time would be "determined later," the Xinhua News Agency reported.
The blast-off was to have taken place just days after China landed a rover on Mars, as it hustles ahead with its extraterrestrial ambitions.
Beijing has pumped billions into its space programme in a bid to make up ground on pioneers Russia and the United States, with ambitious projects in Earth orbit and the landing of uncrewed craft on the Moon and Mars.
But it was heavily reprimanded by the United States and many experts for a potentially dangerous breach of space etiquette for letting a massive rocket segment free-fall to Earth earlier this month after launching the core module of China's space station.

Paris (ESA) May 20, 2021
The International Space Station's largest scientific instrument celebrates a decade in orbit. Wednesday 19 May 2021 marks 10 years since the cosmic-ray-hunting Alpha Magnetic Spectrometer (AMS-02) was installed on the exterior of the Space Station.
AMS-02 is a sub-atomic particle detector that looks for dark matter, antimatter and measures cosmic rays. It took 16 countries and nearly 20 ye

Liege, Belgium (SPX) May 20, 2021
A team of researchers at the Centre Spatial de Liege (CSL) of the University of Liege has just developed a method to identify the contributors and origins of stray light on space telescopes. This is a major advance in the field of space engineering that will help in the acquisition of even finer space images and the development of increasingly efficient space instruments.

Chinese Mars rover beams back first photos

Beijing (AFP) May 19, 2021
Solar panels against an alien landscape, ramps and rods pointing at the Martian horizon - China's first probe on the Red Planet has beamed back its first "selfies" after its history-making landing last week.
The Zhurong rover was carried into the Martian atmosphere in a lander on Saturday, in the first ever successful probe landing by any country on its first Mars mission.

Heavy metal vapors unexpectedly found in comets throughout our Solar System

Munich, Germany (SPX) May 20, 2021
A new study by a Belgian team using data from the European Southern Observatory's Very Large Telescope (ESO's VLT) has shown that iron and nickel exist in the atmospheres of comets throughout our Solar System, even those far from the Sun. A separate study by a Polish team, who also used ESO data, reported that nickel vapour is also present in the icy interstellar comet 2I/Borisov. This is the fi

Melbourne, Australia (The Conversation) May 20, 2021
China's Zhurong rover landed safely on Mars on May 15, making China only the third country to successfully land a rover on the red planet.
More impressively still, China is the first Mars-going nation to carry out an orbiting, landing and rovering operation as its first mission.

Krakow, Poland (SPX) May 20, 2021
Unbound nickel atoms and other heavy elements have been observed in very hot cosmic environments, including the atmospheres of ultra-hot exoplanets and evaporating comets that ventured too close to our Sun or other stars. A new study conducted by JU researchers reveals the presence of nickel atoms in the cold gasses surrounding the interstellar comet 2I/Borisov. The team's finding is being publi
