Gaia: Rewriting the story of the Milky Way
For over a decade, ESA’s Gaia mission has mapped our galaxy with stunning precision—rewriting the story of the Milky Way. As its mission enters a new phase, we look back at its most groundbreaking discoveries.
Webb Sees an Early Galaxy Blowing Away the Cosmic Fog
When the James Webb Space Telescope was launched in December 2021, one of its primary purposes was to see the first galaxies in the Universe forming just a few million years after the Big Bang. In true JWST style though, it has surpassed all expectations and now, a team of astronomers think they have gone even further back, seeing one galaxy clearing the early fog that obscured the Universe! The image represents a point in time 330 million years after the Big Bang and reveals a bright hydrogen emission from the fog surrounding a galaxy. It was somewhat unexpected though as current models predict it would have been blown away long ago!

Hubble Spots a Chance Alignment This NASA/ESA Hubble image features the spiral galaxy NGC 5530. ESA/Hubble & NASA, D. Thilker
The subject of today’s NASA/ESA Hubble Space Telescope image is the stunning spiral galaxy NGC 5530. This galaxy is situated 40 million light-years away in the constellation Lupus, the Wolf, and classified as a ‘flocculent’ spiral, meaning its spiral arms are patchy and indistinct.
While some galaxies have extraordinarily bright centers that host a feasting supermassive black hole, the bright source near the center of NGC 5530 is not an active black hole but a star within our own galaxy, only 10,000 light-years from Earth. This chance alignment gives the appearance that the star is at the dense heart of NGC 5530.
If you pointed a backyard telescope at NGC 5530 on the evening of September 13, 2007, you would have seen another bright point of light adorning the galaxy. That night, Australian amateur astronomer Robert Evans discovered a supernova, named SN 2007IT, by comparing NGC 5530’s appearance through the telescope to a reference photo of the galaxy. While it’s remarkable to discover even one supernova using this painstaking method, Evans has in fact discovered more than 40 supernovae this way! This particular discovery was truly serendipitous: it’s likely that the light from the supernova completed its 40-million-year journey to Earth just days before Evans spotted the explosion.

Webb Sees Neptune's Auroras for the First Time
The outer planets remain somewhat of a mystery and Neptune is no exception. Voyager 2 has been the only probe that has visited the outermost planet but thankfully the James Webb Space Telescope is powerful enough to reveal it in all its glory. With its cameras regularly fixed on Neptune it has even picked up auroral activity in some of its latest images. The data was gathered back in 2023 using Webb’s Near-Infrared spectrograph which detected the tell tale sign of auroral activity, an emission line of trihydrogen cation. The element appears on other giant planets too when aurora are present.

IRIDE first image presented at ESA–ESRIN
The first image from a new Italian Earth observation satellite mission was published today: a high-resolution image of a strip of the Italian peninsular showing the city of Rome at a resolution of 2.66 metres. This is three times higher than the resolution currently available for systematic acquisition over Italy.
