This Week's Sky at a Glance, May 1 – 9
Venus hangs in place in the western twilight while Aldebaran and the Pleiades continue their downward slide behind it. And if Venus is the Evening Star, then bright Jupiter, high to its upper left, counts as the False Evening Star.

Sentinel-1D goes live: a milestone for Europe’s radar mission
The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase.
With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission – a journey that began more than a decade ago and that has helped pave the way for the future of Earth observation.

New Lithium-Plasma Engine Passes Key Mars Propulsion Test
You’re on the fourth human mission to Mars, and you’re told the Odyssey spacecraft designed to take you there will be the smoothest ride you’ll ever take. It features a newly christened electric propulsion engine which was in the late stages of testing during the first three missions. The mission starts and the spacecraft travels at a crawl, and you wonder if it’s broken. A week goes by and you’re now traveling at more than 400,000 kilometers (250,000 miles) per hour, and your mind is blown as to how fast you’re going, how quickly that happened, and that this mission might be more awesome than you thought.
NASA Invites Media to Ireland Artemis Accords Signing
Ireland will sign the Artemis Accords during a ceremony at 3 p.m. EDT Monday, May 4, at NASA Headquarters in Washington.
NASA Administrator Jared Isaacman will host Ambassador of Ireland to the United States of America Geraldine Byrne Nason; Minister for Enterprise, Tourism and Employment Peter Burke, T.D., of Ireland; and U.S. Department of State officials for the ceremony.
This event is in person only. Media interested in attending must RSVP no later than 12 p.m. on May 4 to: hq-media@mail.nasa.gov. NASA’s media accreditation policy is online.
In 2020, during the first Trump Administration, the United States, led by NASA and the State Department, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies.
The accords introduced the first set of practical principles aimed at enhancing the safety, transparency, and coordination of civil space exploration on the Moon, Mars, and beyond.

What is the Most Common Type of Planet in the Galaxy?
Astronomers now believe there is at least one planet for every star in the Milky Way but new research has revealed a deeply unsettling twist in that picture. The most common planets in our Galaxy, it turns out, are almost entirely absent around the most common stars. Using data from NASA's TESS satellite, researchers found that the small, faint stars that make up the vast majority of the Milky Way seem to host rocky super Earths in abundance, but virtually no sub Neptunes, the planet type previously thought to be plentiful. The finding doesn't just refine existing theories of planet formation, it rewrites them.
At shadow climate summit on phasing out fossil fuels, scientists are center stage
Representatives of more than 50 nations gathered in Santa Marta, Colombia, this week at what was billed as the first global summit on phasing out fossil fuels. A panel of scientists will be advising them
How do you study something you can never step outside of?
An international team of astrophysicists has just released one of the largest cosmological datasets ever assembled. A mouthwatering 2.5 petabytes of simulated universe, freely available to researchers anywhere in the world. Built using a supercomputer and a suite of simulations called FLAMINGO, the data models how matter has evolved since the Big Bang, tracing everything from individual galaxies to the vast cosmic web that stretches across billions of light years.
What does it take to call home from the Moon?
When NASA's Artemis II crew swung around the Moon in April, the world watched in extraordinary detail and a breakthrough laser communications system was the reason why. Bolted to the outside of the Orion capsule, a compact optical terminal beamed 484 gigabytes of data back to Earth using invisible infrared light, outpacing traditional radio systems by a factor of tens. The result was some of the most vivid imagery ever captured in deep space, and a technology demonstration that will fundamentally change how humanity communicates beyond Earth.
Scientists just discovered what is fueling cows’ potent burps

How Do Close Binary Stars Form?
Our Sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of Sun-like stars are locked in with more than one companion star. If there are two, it’s known as a “binary” system, but in many cases there are even more stars all collectively tied together by gravity. Astronomers have long debated why this happens, and a new paper, available in pre-print on arXiv from Ryan Sponzilli, a graduate student at the University of Illinois, makes an argument for a mechanism known as disk fragmentation.
