NASA says 2019 was the second warmest year ever recorded

NASA says 2019 was the second warmest year ever recorded

Last year was the second warmest recorded year since humans started keeping track of global temperatures in the late 1800s, according to a joint release from NASA and the National Oceanic and Atmospheric Administration (NOAA). The space agency says that it and NOAA conducted independent analyses of the data and both came to the same conclusion. At this point in time, the only hotter year on record is 2016, meaning the last half-decade has officially been the warmest in 140 years.

Scientists create “xenobots” using living cells

Scientists create “xenobots” using living cells

A team of scientists from the University of Vermont working with researchers from other institutions, has been able to repurpose living cells. The cells used were scraped from Frog embryos and assembled into new lifeforms. The new lifeforms are millimeter-wide "xenobots" that can move towards a target. They may also be able to pick up a payload, such as a medication, that needs to be delivered to a specific place inside the person. The xenobots can also heal themselves after being cut.

NASA tests VIPER lunar rover to prepare for future water mission

NASA tests VIPER lunar rover to prepare for future water mission

At its Glenn Researcher Center in Cleveland, NASA researchers tested a rover called 'VIPER' that will be used to search for water ice at the Moon's south pole. The robot is officially called the Volatiles Investigating Polar Exploration Rover; it is around the size of an ordinary golf cart, according to the space agency, and it was designed by engineers with NASA's Johnson Space Center in Texas.

Scientists discover stardust older than the Sun in a meteorite

Scientists discover stardust older than the Sun in a meteorite

Fifty years ago, in Australia, scientists discovered a meteorite that has been under study. The team has now found that the stardust inside the meteorite formed between 5 and 7 billion years ago. That makes it the oldest material ever found on Earth. Scientist Philipp Heck says that the material is the oldest ever found and that it tells about how stars formed in our galaxy.

A new source of magnetic storms is closer to Earth than expected

A new source of magnetic storms is closer to Earth than expected

Magnetic storms have the potential to impact the daily lives of people all around the globe and to threaten satellites. A new study from the NASA THEMIS mission team has shown that magnetic storms can originate much closer to Earth than previously thought. The study is the first to show that the storms can form close to Earth and to indicate that the storms could overlap the orbits of weather, communication, and GPS satellites.

ESA’s Mars Express snaps stunning image of Red Planet’s icy cap

ESA’s Mars Express snaps stunning image of Red Planet’s icy cap

The European Space Agency has shared a new image of Mars captured using the camera on its Mars Express spacecraft. In the photo, we see Mars' north pole covered with large sheets of snowy white ice surrounded by otherwise reddish and dusty landscape. The image is surprisingly clear and smooth, resembling something one may capture with a 4K drone camera or DSLR.

Scientists create lightweight 18-carat gold using ordinary plastic

Scientists create lightweight 18-carat gold using ordinary plastic

Researchers with ETHzurich have successfully used plastic to create lightweight gold that retains its purity, according to a recent announcement from the institution. The lightweight gold is ideally suited for products like jewelry and watches -- things that would benefit from a reduction in weight without a loss in gold purity or beauty.

These are NASA’s newest astronauts

NASA has revealed its newest astronauts, the future crews for missions to the Moon and, eventually, Mars. Eleven new additions have been made to NASA's exclusive ranks, though even then the total number of active astronauts cleared for crewed missions remains small.

ESA XMM-Newton X-ray observatory sees hot gas sloshing in a galaxy

ESA XMM-Newton X-ray observatory sees hot gas sloshing in a galaxy

The ESA has announced that it has used the XMM-Newton X-ray observatory to view hot gas sloshing around inside a galaxy cluster for the first time. This behavior may have been driven by turbulent merger events. The ESA says that galaxy clusters are the largest systems in the Universe bound together by gravity.

Hubble Space Telescope detects smallest dark matter clumps ever

NASA has announced that the Hubble Space Telescope has detected the smallest known dark matter clumps using a new observation technique. The technique has confirmed that dark matter forms much smaller clumps than previously known. NASA says that the result confirms a fundamental prediction of the "cold dark matter" theory.

NEID instrument lets scientists determine the density of distant planets

NASA and the National Science Foundation funded a new instrument called NEID. NEID is designed to help scientists to measure the masses of planets that are outside of our solar system. The tool observes the gravitational pull that planets exert on their parent stars.

NASA Artemis rocket takes same ferry trip as Apollo 11

NASA Artemis rocket takes same ferry trip as Apollo 11

This week NASA loaded their first Artemis mission Space Launch System (SLS) Rocket Core Stage onboard the Pegasus barge in New Orleans. This stage of the hardware needed for Artemis was loaded onboard the barge on January 8th with plans to deliver to NASA’s Stennis Space Center near Bay St. Louis, Mississippi. This ferry journey mimics that of the NASA Apollo missions in the 1960s and 1970s.
