Scientists Urge NASA to Send a Space Mission to Uranus

Specifically, the researchers are calling on NASA to create the Uranus Orbiter and Probe, or UOP. The mission concept involves sending a spacecraft into orbit around Uranus, along with a probe that will dive into the planet's atmosphere.

The Universe's Expansion Could Be Coming to an End

According to cosmologists, "soon" is within 100 million years. This means that humankind is on the verge of the beginning of the era of the Big Crunch. Physicists published their study in Proceedings of the National Academy of Sciences.

Telescope Captures an Image of a Dead Star's Shroud

EGB 6 will exist another few thousand years. After that, the stellar core will cool down and turn into a faint white dwarf, which will stop emitting enough ultraviolet light to ionize the ejected envelope.

Astronomers Discover an Ultra-Faint Satellite of Milky Way

Pegasus IV is classified as an ultra-faint galaxy. Such objects are characterized by extremely low brightness but are rich in mysterious dark matter. Ultra-faint galaxies are thought to be very ancient objects, formed shortly after the Big Bang.

Astronomers Confirm the Existence of Ice Deposits at Mercury's Poles

A team of U.S. researchers combined the data it collected with MESSENGER observations and created the most detailed map of water ice deposits on Mercury and even determined its degree of purity.

LAMOST Discovered Over 1,500 Compact Galaxies

Of the 1,417 new compact galaxies, 739 are Green Pea galaxies, 270 are Blueberry galaxies, and 388 are Purple Grape galaxies. These classes of stellar systems have received such strange names relatively recently because of their appearance.

CAPSTONE Lunar Cubesat Mission Is Ready for Launch

It is the first mission undertaken as part of the Gateway near-lunar orbital station program. CAPSTONE will have to test the orbit where the new space outpost of humankind is planned to be placed.

Jupiter's Twin Was Spotted 17,000 Light-Years Away

This is the first time in the history of science that the telescope has been able to detect an extrasolar planet through a microlensing event. Kepler wasn't really designed for such observations.

NASA May Still Rename the James Webb Space Telescope

Opponents of the name are calling for the project to be renamed because of the alleged bad reputation of James Webb himself. People remembered that during his time in the federal government, he fueled discrimination against the LGBT community.

Sunspot Activity Is Exceeding All Predictions

The increase in the number of sunspots will also directly affect the number and power of flares, which can cause communications blackouts, power grid fluctuations and spectacular auroras.

Astronomers Discover Two Saturn-Mass Exoplanets

The discovery was made using the radial-velocity method within the CARMENES survey. The essence of the method is to find the characteristic "wobbles" of stars caused by the gravity of their invisible companions.

Mars Reconnaissance Orbiter Captures Dry Ice on Mars

Dry ice is formed by the freezing of carbon dioxide from the Martian atmosphere. In midwinter, this frost reaches from the poles down to the middle latitudes, up to 50° latitude.
