ESO: VLT uncovers closest pair of supermassive black holes yet found

The latest report from  ESO (European Southern Observatory):

ESO telescope uncovers closest pair of supermassive black holes yet

This image shows close-up (left) and wide (right) views of the two bright galactic nuclei, each housing a supermassive black hole, in NGC 7727, a galaxy located 89 million light-years away from Earth in the constellation Aquarius. Each nucleus consists of a dense group of stars with a supermassive black hole at its centre. The two black holes are on a collision course and form the closest pair of supermassive black holes found to date. It is also the pair with the smallest separation between two supermassive black holes found to date — observed to be just 1600 light-years apart in the sky.   The image on the left was taken with the MUSE instrument on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile while the one on the right was taken with ESO’s VLT Survey Telescope.

Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of supermassive black holes and will eventually merge into one giant black hole.

Located in the galaxy NGC 7727 in the constellation Aquarius, the supermassive black hole pair is about 89 million light-years away from Earth. Although this may seem distant, it beats the previous record of 470 million light-years by quite some margin, making the newfound supermassive black hole pair the closest to us yet.

Supermassive black holes lurk at the centre of massive galaxies and when two such galaxies merge, the black holes end up on a collision course. The pair in NGC 7727 beat the record for the smallest separation between two supermassive black holes, as they are observed to be just 1600 light-years apart in the sky.

“It is the first time we find two supermassive black holes that are this close to each other, less than half the separation of the previous record holder,”

says Karina Voggel, an astronomer at the Strasbourg Observatory in France and lead author of the study published online today in Astronomy & Astrophysics.

“The small separation and velocity of the two black holes indicate that they will merge into one monster black hole, probably within the next 250 million years,”

adds co-author Holger Baumgardt, a professor at the University of Queensland, Australia. The merging of black holes like these could explain how the most massive black holes in the Universe come to be.

Voggel and her team were able to determine the masses of the two objects by looking at how the gravitational pull of the black holes influences the motion of the stars around them. The bigger black hole, located right at the core of NGC 7727, was found to have a mass almost 154 million times that of the Sun, while its companion is 6.3 million solar masses.

Just as people at a busy crossroad may accidentally bump into each other, so too can galaxies in the Universe! But in this case, the outcome is more dramatic than a small nudge. When two galaxies clash, they merge into each other, giving birth to a new, bigger one. One example is the NGC 7727 galaxy, shown in this image from ESO’s VLT Survey Telescope (VST) in Chile. Located 89 million light-years away from Earth in the constellation Aquarius, NGC 7727 is believed to be the result of a clash between two galaxies that occurred about one billion years ago. The consequences of this tremendous cosmic bump are still evident in the peculiar, irregular shape of NGC 7727 and the streams of stars in its outer regions.  The image was taken in visible light as part of the VST-ATLAS survey. The goal of the survey is to map a vast region of the Southern Sky — so large you could fit about 19,000 full moons in it! By studying the galaxies in this region, astronomers aim to shed new light on the nature of dark energy, the mysterious force permeating the Universe and causing its accelerating expansion.

It is the first time the masses have been measured in this way for a supermassive black hole pair. This feat was made possible thanks to the close proximity of the system to Earth and the detailed observations the team obtained at the Paranal Observatory in Chile using the Multi-Unit Spectroscopic Explorer (MUSE) on ESO’s VLT, an instrument Voggel learnt to work with during her time as a student at ESO. Measuring the masses with MUSE, and using additional data from the NASA/ESA Hubble Space Telescope, allowed the team to confirm that the objects in NGC 7727 were indeed supermassive black holes.

Astronomers suspected that the galaxy hosted the two black holes, but they had not been able to confirm their presence until now since we do not see large amounts of high-energy radiation coming from their immediate surroundings, which would otherwise give them away.

“Our finding implies that there might be many more of these relics of galaxy mergers out there and they may contain many hidden massive black holes that still wait to be found,says Voggel. “It could increase the total number of supermassive black holes known in the local Universe by 30 percent.”

The search for similarly hidden supermassive black hole pairs is expected to make a great leap forward with ESO’s Extremely Large Telescope (ELT), set to start operating later this decade in Chile’s Atacama Desert.

“This detection of a supermassive black hole pair is just the beginning,” says co-author Steffen Mieske, an astronomer at ESO in Chile and Head of ESO Paranal Science Operations. “With the HARMONI instrument on the ELT we will be able to make detections like this considerably further than currently possible. ESO’s ELT will be integral to understanding these objects.”

Outpost in Orbit:
A Pictorial & Verbal History of the Space Station

Nanoracks to deploy FEES2 picosat from the ISS

Nanoracks and GP Advanced Projects (GPAP) will soon deploy a picosat a third the size of a standard CubeSat from the International Space Station.  GPAP refers to its picosat design as a 1/3U CubeSat (10cm x 10cm x 3cm). The first demo reached orbit in 2020 and was called the Flexible Experimental Embedded Satellite  or FEES.

FEES is a 1/3U Cubesat for in-orbit demonstration and validation of electronic components.

Cubesats systems were born in 1999 as a result of the cooperation between California Polytechnic State University and Stanford University, which defined the standards of this new satellite category. Typical Cubesats have a 10x10x10 cm dimension, 1U volume and are nominally in the nanosat or picosat satellite class.

These attributes being set, Cubesats allow affordable cost launch and different applications, since they lend themselves to educational, scientific and commercial purposes.

More than fifteen years later than the first cubesat prototype, we knew we could go even further. This vision led us to the development a 1/3U Cubesat, miniaturising the Cubesat technology in just 30% of former volume. FEES is the result of our commitment to this project.

Incredible partners like Politecnico di Milano, Brno University of Technology, CESI, LINKIT, Laser and Pandigital joined us in the program, giving birth to a 10x10x3cm satellite with a 300g mass which has been launched into orbit in October 2020.

Here is the announcement of the deployment of second FEES satellite (FEES2) into orbit, this time from the ISS:

Nanoracks to Deploy First-Ever 0.3U CubeSat from Space Station

NOVEMBER 23, 2021 – Torino, Italy – Nanoracks Europe is on track to set a new record as the company prepares to deploy the first-ever 0.3U CubeSat from the International Space Station (ISS). The satellite, named FEES2, was developed by the Italian company GP Advanced Projects and is approximately the thickness of a cherry. It will be one of the smallest trackable objects deployed directly from the Space Station.

FEES2 (Flexible Experimental Embedded Satellite-2) is a platform for demonstrating and validating CubeSat technology in orbit. The mission will test critical satellite components, such as GPS receivers and attitude control systems that have specifically been designed for miniaturized experiments.

GP Advanced Projects (GPAP) selected Nanoracks Europe for the integration services, launch brokerage, and deployment of FEES2 in June 2021 to reach orbit quickly and efficiently. Nanoracks’ proven business model provides flexible opportunities for its customers to demonstrate innovative technologies utilizing the ISS.

Guido Parissenti, CEO and co-founder of GPAP, remarked that

“The ISS has been a sort of booster for our company’s growth. Thanks to this deployment opportunity, which we contracted just five months ago, we will reach a major milestone towards the building of the first Italian nanosatellite constellation for IoT [Internet of Things], which is our long-term goal.”

The miniaturization of space technologies is a trend that allows for broader participation in space research and for CubeSat developers to make progress more rapidly. Companies like GP Advanced Projects that are seeking to deploy small satellites might have had difficulties reaching orbit in the past due to funding or launch accommodations. This mission demonstrates that such deployments are not only possible but that they can also be completed in a very short amount of time.

To approve FEES2 for deployment from the ISS, Nanoracks performed a feasibility study with NASA to verify the satellite’s trackability and quantify its deployment parameters. After careful evaluation, FEES2 was approved for integration into a Nanoracks CubeSat Deployer (NRCSD). The satellite is now integrated into an NRCSD with several other CubeSats and is manifested on the 24th SpaceX Commercial Resupply (SpX CRS-24) mission to the ISS, which is planned to launch in December 2021.

“We were excited that GP Advanced Projects entrusted Nanoracks to get the job done,”

said Adriana Aiello, Systems Engineer for Nanoracks Europe.

“Of course, we were going to make this happen for GP Advanced Projects – this is our specialty. Our customers’ needs challenge us to be innovators and disruptors, and we’re proud to bring a new customer and new technology to the Space Station.”

[Nanoracks Europe’s CEO, Veronica La Regina, said,]

“This is an absolutely exciting opportunity for Nanoracks Europe to make a difference in enabling wider access to space in our community,” […] . “Nanoracks’ passion for opening space access is one of our greatest assets, and this mission proves to be yet another example of the tenacity for making new things happen.”

Nanoracks offers a variety of satellite launch opportunities, including deployments from the International Space Station, the Northrop Grumman Cygnus spacecraft, the SpaceX Rideshare program, and from India’s PSLV. Learn more about Nanoracks’ satellite opportunities here.
