Why is Pluto no longer considered a planet?
Since 2006, Pluto was classified as "minor planets and asteroids”.
Scientists were forced to revise the classification by the discovery of Ceres and Eris. They, like Pluto, have not yet cleared their orbit of extraneous celestial bodies. In addition, Pluto cannot be considered the most massive body in its neighborhood.
Therefore, despite the presence of an atmosphere and its own satellite, it is still not considered the ninth planet.

Magnetar Artistic Concept
On December 27, 2004, a gamma ray burst from SGR 1806-20 arrived in the solar system. The burst was so powerful that it impacted Earth's atmosphere more than 50,000 light-years away.
The magnetar emitted more energy in one tenth of a second than the Sun emits in 100,000 years. The outburst is considered the largest explosion in the galaxy since the supernova SN 1604, observed by Johannes Kepler in 1604.

On April 9, a huge prominence was observed over the southern hemisphere of the Sun, with a total length of about 1 million km!
There is no data yet on how many hours it lasted.
The animation above is made for you from the latest images from the solar space observatory. Enjoy with us.

The universe's most powerful magnets
There are objects in the universe with extremely powerful magnetic fields. Even within a radius of 1000 kilometers around it, life would be impossible due to distortions of electron clouds of atoms under the influence of its magnetic field.
This object is a magnetar - a neutron star, the first evidence of whose existence was obtained in 1998 by observing a powerful flash of gamma-ray and X-ray radiation. Today scientists know of 30 magnetars.
The diameter of such a star is about 20 km and its mass is about 1.4 solar masses. They are formed from massive stars with a mass 10-25 times the mass of the Sun.
The density of the inside of a magnetar is such that a tablespoon of its matter weighs more than 100 million tons.😱

Hubble is again delighting with beautiful photos: this time the telescope has captured a group of three galaxies in the Phoenix constellation, known collectively as NGC 7764A.
The three galaxies are individually labeled NGC 7764A1, NGC 7764A2 and NGC 7764A3. If you get a little fancy, it might look like the two galaxies in the upper right corner resemble the USS Enterprise, the Constitution-class starship of Starfleet from Star Trek. NGC 7764A is located about 425 million light-years from Earth.
What's really going on in the picture?
We can only guess. It is possible that galaxies collided or interacted, resulting in tails of stars and gas.

Neptune is experiencing strange temperature fluctuations
The temperature of Neptune's atmosphere is undergoing strange spikes, and it may take scientists decades to understand exactly what's happening on this distant planet.
The ice giant's global temperature dropped about 8 degrees Celsius between 2003 and 2012. Then from 2018 to 2020, thermal imagery shows the planet's south pole became dramatically brighter, indicating a surge of 11 degrees Celsius.

The Kuiper Belt and the Oort Cloud
✔️The Kuiper Belt is a large cluster of icy objects at the edge of our solar system
✔️Oort Cloud is a spherical formation containing comets and other objects.
After the discovery of Pluto in 19Z0, scientists began to speculate that it was not the most distant object in the system. Co time, they noted the movements of other objects and in 1992 found a new site.
The Kuiper Belt can hold hundreds of thousands of icy objects, whose size varies between small fragments up to 100 km wide. More than a trillion comets could be lurking in the main part of the Kuiper Belt.

What does a pulsar look like?
If you peek at a pulsar in the sky, it appears to be an ordinary shimmering star following a certain rhythm.
In fact, their light does not flicker or pulsate, and they do not appear to be stars. A pulsar produces two persistent narrow beams of light in opposite directions.
The flickering effect is created because they rotate (lighthouse principle). At this moment the beam hits the Earth and then turns again. Why does this happen? The reason is that the light beam of the pulsar is usually not aligned with its rotation axis.

Cyclone Remal is expected to reach the West Bengal coast on May 26, with an orange alert issued for several districts.
The name 'Remal' for the cyclone in formation above the Bay of Bengal has been suggested by Oman and means 'sand' in Arabic.

What causes solar flares?
These phenomena occur because the Sun has its own magnetic field. And flares occur in areas where magnetic fields of opposite polarity collide in a confined space.
Even though we already realize what solar flares are, scientists still can't predict when they will happen. So they commonly take us by surprise.

The most powerful stratospheric winds were detected at Jupiter's poles 🧐
Astronomers have made the first direct measurements of wind speeds in Jupiter's mid-atmosphere. With the help of the Shoemaker-Levy 9 comet. It spectacularly crashed into the gas giant in 1994, leaving new molecules in its stratosphere after its death, which have been carried in it by the winds ever since.
Astronomers are observing the movements of hydrogen cyanide brought by Comet Shoemaker-Levy 9 and managed to measure the speed of the winds in Jupiter's stratosphere.
The jets detected in this part of Jupiter have an average speed of about 600 km/hour.

Axiom Space to send self-assembling robots to the ISS 🦾
The Ax-1 mission will depart April 8 on the Crew Dragon spacecraft. Four people will spend 10 days in orbit. In addition to various biomedical experiments, the team will perform work on the TESSERAE program.
TESSERAE is a research program whose ultimate goal is the self-assembly of structures in space. Its individual modules will be densely packed at launch, but once activated will form a robotic swarm suitable for self-assembly of various elements.
