During the holidays of 2020, there was a remarkable cosmic imagination, from Hubble’s thirtieth birthday picture to shots of a brave pattern on an asteroid. Here is a selection of this year’s offers.
Hubble’s Cosmic Reef
The Hubble Space Telescope, one of the most important scientific instruments, celebrated its thirtieth anniversary in April.
On this occasion an amazing film was released Representation of the star formation region near our Milky Way.
In this beautiful Hubble photograph, the giant red nebula (NGC 2014) and its small blue neighbor (NGC 2020) reside in the Large Magellanic Cloud, a Roman galaxy satellite 163,000 light-years away.
Nebulae are huge clouds of dust and gas that form stars.
At the heart of NGC 2014 are a cluster of bright stars 10 to 20 times the size of our Sun.
The image was nicknamed the “Cosmic Reef” because astronomers thought the nebula resembled an underwater world.
BBC Horizon DocumentaryTo mark the anniversary, they exhibited stunning 3D scenes of Hubble paintings – for example, creating columns that are part of the Eagle Nebula.

Hold the asteroid
Nasin introduced Osiris-Rex this year Applies strategy with the brave asteroid BenSo rock and soil samples can be delivered to the ground.
Asteroids like Bianu have been pristine since the beginning of the Solar System. They are the spatial building blocks of the planets, and open up a view of how the Earth-like world came into being.
Osiris-Rex used a long bracket with a long collection chamber to collect the samples. When the nitrogen class reached the surface of the asteroid, the spacecraft reached the surface of Benu.
This gas stirred the surface of the beans and the asteroid fragments floated in the storage chamber.
The strategy seems to have worked as shown in the order of the pictures above.
Meanwhile, on December 5, the Japanese mission returns to Earth with its precious cash to collect samples from another asteroid. The Hayabusa-2 spacecraft has released its sample return capsule The Australian arrived safely in the desert.
Samples will be analyzed at a curator in Sagamihara, Japan.
Proximity to the sun
Pictures of Daniel’s Inno Solar Telescope (DKIST) were released in Hawaii in January. He painted the sunny surface with striking details.
The images show cell-like structures about the size of the state of Texas. They are a mass of hot, excited gas or plasma.
Bright areas indicate where this material is growing; Between the dark streets where cold plasma sinks.
DKST is a new facility on the 3,000 – foot – high volcano on Howell Island in Hawaii, Maui.
Scientists want to use it to find new insights into the dynamic nature of our parent star, hoping that they will be able to better predict its energy bursts.
These large explosions of charge particles will destroy the satellites orbiting the Earth, destroy the astronauts and destroy the power grid.
Jupiter is flying
NASA’s Juno spacecraft, launched in 2011, continues to send stunning images from Jupiter, the largest planet in the Solar System.
On June 2, when the world’s closest 27th plane was shown to the world, the gas giant’s rotating cloud captured the imaginary probe of the deck.
Citizen scientist Kevin M. Gill turned the data into a video that brings together 41 images taken during the nearby Juno Pass.
Photos were digitally displayed into a sphere using a virtual “camera” that allowed Jupiter to be viewed from different angles.
Among other things, the most striking feature of the images is Jupiter, a giant red dot – this is actually a severe storm.
Elon Musk’s vehicle, which has looked like a rocket ship since the golden age of science fiction – will, of course, take people to the Red Planet.
In December, SpaceX tests the first complete prototype of the vehicle, 12.5 km directly from the platform to the Boca Chika plant in South Texas.
Because the images are not from space, we are somehow deceived by the inclusion. But we can see this one day, not in the distant future.
The test flight showed some features of the spacecraft, including methane-burning Rapouter engines and the flight path, which descended to the ground just after turning vertically just before landing.
At this point in the test, Maska described the prototype starship pad, the SN8, as being slightly faster and stiffer, an unplanned rapid disassembly. In other words, an accident.
But Flight SpaceX will provide a great deal of engineering data that will help improve the vehicle. The next prototype – the SN9 – is waiting at the plant on the launch pad.
