ESA at 50: looking back and launching forward
The European Space Agency marked its 50th anniversary in May, kicking off a landmark year of mission launches and strategic planning. With the ESA Ministerial Council set to meet in November, Director General Josef Aschbacher reflected on five decades of progress and outlined the agency's future in exploration, climate science, navigation, and global collaboration.
Since its founding in 1975, ESA has contributed to a broad range of scientific and technological areas. One of its most notable moments came in 2014 with the Rosetta mission, when the Philae lander became the first human-made object to land on a comet. The event drew global attention and is considered a major milestone in robotic space exploration.
Copernicus and Galileo
ESA has also developed long-running programmes such as Copernicus and Galileo, which continue to serve scientific, environmental, and practical purposes. Copernicus, the European Union's Earth observation programme, uses satellite data to monitor environmental changes. According to ESA Director General Josef Aschbacher, 'Without those satellites that we have built - and Europe has built many of those - we would not understand the extent of climate change.'

Rare Jupiter-sized planet discovered 3,200 light-years away using Einstein's space-time warping method
Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 light-years from Earth in the galactic bulge. It takes AT2021uey b 4,170 days to orbit its dwarf star, according to a study published in the journal Astronomy & Astrophysics. According to Live Scence, AT2021uey b's shadow was first spotted in 2021 in data taken by the European Space Agency's Gaia telescope. It took the astronomers multiple check-ins to confirm the details of the planet. The astronomers discovered the planet using microlensing, a method used only three times previously, according to the study. Microlensing, which is based on Einstein's theory of relativity, relies on massive objects moving through the galaxy to warp the fabric of the universe, called space-time. Dr. Marius Maskoliunas, astronomer at Vilnius University and co-author of the study, discussed in a statement posted in just how much work goes into using this method. "This kind of work requires a lot of expertise, patience and, frankly, a bit of luck. You have to wait for a long time for the source star and the lensing object to align and then check an enormous amount of data," Maskoliunas said in the statement. "Ninety percent of observed stars pulsate for various other reasons, and only a minority of cases show the microlensing effect." According to the study, microlensing occurs when a massive celestial body briefly positions itself directly in front of an even more distant star. As the planet settles in front of the star during its journey, the light begins to curve around the planet, magnifying the light of the star. According to the study, this temporary magnified light is what astronomers are searching for. Maskoliunas gave an example of how to imagine how microlensing works. "What fascinates me about this method is that it can detect those invisible bodies. Imagine a bird flying past you. You don't see the bird itself and don't know what color it is — only its shadow," Maskoliunas said in the statement. "But from it, you can, with some level of probability, determine whether it was a sparrow or a swan and at what distance from us. It's an incredibly intriguing process." According to Live Science, there have been nearly 6,000 planets discovered since 1992 using two other more common practices known as transmit photometry and radial velocity. These more common practices will detect planets through host stars becoming dimmer due to said planets. They will also detect the wobble of the planets' gravitational pulls that occur.

Unprecedented view of our neighboring Andromeda Galaxy revealed
A new composite image of the Andromeda Galaxy is offering an unprecedented view of our closest spiral galactic neighbor. Composed by NASA and international space partners, the image combines data from more than a dozen telescopes and ground-based observatories. Advertisement Located about 2.5 million light-years from Earth, Andromeda, which is also known as Messier 31m has been a focus of the space community for more than a century, with early observations dating back to at least 1923 by astronomer Edwin Hubble. A key focus of ongoing studies has been the galaxy's evolution and structure, which shares many similar features with our own Milky Way. The new imagery weaves together data from X-rays captured by NASA's Chandra telescope, the European Space Agency's XMM-Newton spacecraft and several other missions to create a unique view of the galaxy's features. 'Each type of light reveals new information about this close galactic relative to the Milky Way. For example, Chandra's X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as well as many other smaller compact and dense objects strewn across the galaxy,' NASA stated.

FOX Weather Unlike the Milky Way, which is difficult to observe from within due to dust, gas and Earth's position inside it, Andromeda can be studied from a great distance, offering astronomers a more complete and unobstructed view. Despite the insights revealed by this image, many mysteries remain about the spiral galaxy, including the composition of invisible dark matter, how it interacts with other cosmic structures and how many stars and planets it truly contains. Advertisement Andromeda is believed to contain hundreds of billions of stars, leading scientists to theorize that it could also host trillions of planets. 3 A key focus of ongoing studies has been the galaxy's evolution and structure, which shares many similar features with our own Milky Way. FOX Weather Even with an army of advanced space technology available today, no telescope is powerful enough to overcome the vast distance and identify a single planet, or, for that matter, even a star, in detail within Andromeda. Advertisement NASA says its upcoming Nancy Grace Roman Space Telescope is among several missions that will help continue to shed light on galaxies like M31. Named after the agency's first chief astronomer, the high-tech observatory is expected to launch in 2027 and will feature a field of view 100 times larger than that of the Hubble Space Telescope.

Hello, neighbor! See the Andromeda galaxy like never before in stunning new image from NASA's Chandra telescope (video)
When you buy through links on our articles, Future and its syndication partners may earn a commission. The galaxy next door to the Milky Way, Andromeda, has never looked as stunning as it does in a new image from NASA's Chandra X-ray space telescope. The image of the galaxy, also known as Messier 31 (M31), was created with assistance from a range of other space telescopes and ground-based instruments including the European Space Agency (ESA) XMM-Newton mission, NASA's retired space telescopes GALEX and the Spitzer Space Telescope as well as the Infrared Astronomy Satellite, COBE, Planck, and Herschel, in addition to radio data from the Westerbork Synthesis Radio Telescope. All these instruments observed Andromeda in different wavelengths of light across the electromagnetic spectrum, with astronomers bringing this data together to create a stunning and intricate image. The image is a fitting tribute to astronomer Vera C. Rubin, who was responsible for the discovery of dark matter thanks to her observations of Andromeda. As the closest large galaxy to the Milky Way, at just around 2.5 million light-years away, Andromeda has been vital in allowing astronomers to study aspects of galaxies that aren't accessible from our own galaxy. For example, from inside the Milky Way, we can't see our galaxy's spiral arms, but we can see the spiral arms of Andromeda. Every wavelength of light that was brought together to create this incredible new image of Andromeda tells astronomers something different and unique about the galaxy next door. For example, the X-ray data provided by Chandra has revealed the high-energy radiation released from around Andromeda's central supermassive black hole, known as M31*. M31* is considerably larger than the supermassive black hole at the heart of the Milky Way, known as Sagittarius A* (Sgr A*). While our home supermassive black hole has a mass 4.3 million times that of the sun, M31* dwarfs it with a mass 100 million times that of the sun. M31* is also notable for its occasional flares, one of which was observed in X-rays back in 2013, while Sgr A* is a much "quieter" black hole. Andromeda was chosen as a tribute to Rubin because this neighboring galaxy played a crucial role in the astronomer's discovery of a missing element of the universe. An element that we now call dark matter. In the 1960s, Rubin and collaborators precisely measured the rotation of Andromeda. They found that the speed at which this galaxy's spiral arms spun indicated that the galaxy was surrounded by a vast halo of an unknown and invisible form of matter. The mass of this matter provided the gravitational influence that was preventing Andromeda from flying apart due to its rotational speed. The gravity of its visible matter wouldn't have been sufficient to hold this galaxy then, astronomers have discovered that all large galaxies seem to be surrounded by similar haloes of what is now known as dark matter. This has led to the discovery that the matter which comprises all the things we see around us — stars, planets, moons, our bodies, next door's cat — accounts for just 15% of the "stuff" in the cosmos, with dark matter accounting for the other 85%. The finding has also prompted the search for particles beyond the standard model of particle physics that could compose dark matter. Thus, there's no doubt that Rubin's work delivered a watershed moment in astronomy, and one of the most important breakthroughs in modern science, fundamentally changing our concept of the universe.

In addition to this tribute image, the Vera C. Rubin Observatory released its first images of the cosmos as it gears up to conduct a 10-year observing program of the southern sky called the Legacy Survey of Space and Time (LSST). Additionally, in recognition of Rubin's monumental contributions to our understanding of the universe, the United States Mint recently released a quarter featuring Rubin as part of its American Women Quarters Program. She is the first astronomer to be honored in the series.
