ESA Herschel @ESAHerschel

A European Space Agency (ESA) mission. Both the most sensitive far-infrared telescope ever put into space &, at 3.5m, the largest space telescope of any kind. esa.int/herschel ESAC, Madrid Joined February 2009

Well done the DART Team. Now, over to our ESA colleagues with the Hera mission for the follow-up!

Happy 13th anniversary of the launch of @ESAHerschel & @Planck, which revolutionized our vision of the cool cosmos. Their data still produces ground-breaking science.

The best prediction that we have is that @ESAHerschel will pass Earth at 14:11UT on October 14th 2027, at 21.6 times the distance of the Moon. It should be easily detected by telescopes that search for asteroids passing close to the Earth.

Right now, @ESAHerschel is slowly emerging from behind the Sun and getting steadily closer to Earth again, passing close to Earth in 2027. It is about magnitude 29, in the constellation of Aries.

If you ever visit the beautiful city of Bath, visit the Herschel Museum (herschelmuseum.org.uk/herschel-200/) where you can visit the garden from which he discovered Uranus & see some of his telescopes.

Tomorrow will be the 13th anniversary of the launch of @ESAHerschel @Planck. And, 2023 marks the 200th anniversary of the death of Sir William Herschel, discoverer of infrared radiation. Scientists around the world continue to use the data obtained by @ESAHerschel & @Planck daily

You have probably noticed that, after something like 15 years, the @ESAHerschel avatar has changed. This is the smart, new-design Herschel mission logo, part of an ESA-wide exercise to improve brand identity.

If you are bored with Venus, some nice quotes about the @ESAHerschel observations of the moons of Uranus in this article: spacedaily.com/reports/Astron…

It has taken several years of careful data analysis, but the result was one of the most remarkable observations by the @ESAHerschel mission. Herschel data is alive and well in the Science Archives at @ESAesdc and still producing amazing science.

You don't always need to send probes to explore the Solar System. Scientists from Germany and Hungary, led by MPIA's Örs Detre, have now analyzed data of the @ESAHerschel to determine that the main Uranian moons are similar to dwarf planets like Pluto. mpia.de/news/science/2…

Herschel-PACS observations of the moons of Uranus: mpia.de/news/science/2… How do you see faint moons apparently hidden by the overwhelming glare of Uranus? The PACS team has done it!

The last two pieces of the Herschel-Planck constellation, as it was termed, were HP04 & HP05. The former seen for 7 days & the latter for 8. Both faded quickly, showed unusual motion & were likely to be just large, rapidly evaporating sheets of ice that detatched from the Ariane.

What has happened with other pieces of @ESAHerschel such as the Ariane Upper Stage & the Sylda? The booster returns around 2022 Mar 30, at a distance of about 0.092 AU, at mag 22.4. The Sylda made two orbits of Earth and escaped. It should return around 2025 April 20 at 0.053 AU.

Many big survey telescopes such as PanSTARRS should be able to pick up both @ESAHerschel & @Planck as they pass by. If they do, we will get an orbit for both that is exact enough to track them accurately for a couple of centuries in the future.

In the next few months, both @ESAHerschel & @Planck will reach their furthest point from the Earth in their respective orbits and start to return. @Planck should be closest on June 8th 2027 (0.086AU) & @ESAHerschel on October 13th 2027 (0.055AU).
