Since a research team released the image of a newly discovered black hole on April 10, 2019, the study of this cosmic body gained much momentum, as it is the smallest black hole on record, and the closest to our planet.

Black holes are characterized with great gravity that nothing, not even particles or electromagnetic radiation like light, can escape. They usually have huge masses, larger than that of the sun. The newest discovery in this field is a black hole called "Unicorn," and it was announced on April 18, in the journal Monthly Notices of the Royal Astronomical Society.

The researchers named it "Unicorn" because of its unique size, and because it was found in Monoceros, a relatively dim constellation that exists to the east of the Orion constellation, and to the north of Sirius star in the constellation Canis Major.

Astronomers at the Ohio State University discovered the new black hole while examining a giant star in the constellation Monoceros, using NASA's Transiting Exoplanet Survey Satellite (TESS) and the Kilodegree Extremely Little Telescope (KELT).

They noticed that the star's light intensity and shape shift in different spots around the orbit, suggesting that another object is tugging on the star and changing its shape. The team believed the object is likely a black hole, and estimated it is a small one.

Although the mass of some black holes is millions of times larger than the sun's, the team estimates that the mass of Unicorn is only three times that of our sun. This indicates that the newly discovered black hole is smaller than the usually discovered ones. Few black holes with such small mass had been found in the universe. Lying a mere 1,500 light-years from us, Unicorn is considered close to the Earth.



Water Levels Plummet at Drought-Hit Iraqi Reservoir

Water Levels Plummet at Drought-Hit Iraqi Reservoir

Water levels at Iraq's vast Dukan Dam reservoir have plummeted as a result of dwindling rains and further damming upstream, hitting millions of inhabitants already impacted by drought with stricter water rationing.

Amid these conditions, visible cracks have emerged in the retreating shoreline of the artificial lake, which lies in northern Iraq's autonomous Kurdistan region and was created in the 1950s.

Dukan Lake has been left three quarters empty, with its director Kochar Jamal Tawfeeq explaining its reserves currently stand at around 1.6 billion cubic meters of water out of a possible seven billion.

That is "about 24 percent" of its capacity, the official said, adding that the level of water in the lake had not been so low in roughly 20 years.

Satellite imagery analyzed by AFP shows the lake's surface area shrank by 56 percent between the end of May 2019, the last year it was completely full, and the beginning of June 2025.

Tawfeeq blamed climate change and a "shortage of rainfall" explaining that the timing of the rains had also become irregular.

Over the winter season, Tawfeeq said the Dukan region received 220 millimeters (8.7 inches) of rain, compared to a typical 600 millimeters.

- 'Harvest failed' -

Upstream damming of the Little Zab River, which flows through Iran and feeds Dukan, was a secondary cause of the falling water levels, Tawfeeq explained.

Also buffeted by drought, Iran has built dozens of structures on the river to increase its own water reserves.

Baghdad has criticized these kinds of dams, built both by Iran and neighboring Türkiye, accusing them of significantly restricting water flow into Iraq via the Tigris and Euphrates rivers.

Iraq, and its 46 million inhabitants, have been intensely impacted by the effects of climate change, experiencing rising temperatures, year-on-year droughts and rampant desertification.

At the end of May, the country's total water reserves were at their lowest level in 80 years.

On the slopes above Dukan lies the village of Sarsian, where Hussein Khader Sheikhah, 57, was planting a summer crop on a hectare of land.

The farmer said he hoped a short-term summer crop of the kind typically planted in the area for an autumn harvest -- cucumbers, melons, chickpeas, sunflower seeds and beans -- would help him offset some of the losses over the winter caused by drought.

In winter, in another area near the village, he planted 13 hectares mainly of wheat.

"The harvest failed because of the lack of rain," he explained, adding that he lost an equivalent of almost $5,700 to the poor yield.

"I can't make up for the loss of 13 hectares with just one hectare near the river," he added.

- 'Stricter rationing' -

The water shortage at Dukan has affected around four million people downstream in the neighboring Sulaimaniyah and Kirkuk governorates, including their access to drinking water.

For more than a month, water treatment plants in Kirkuk have been trying to mitigate a sudden, 40 percent drop in the supplies reaching them, according to local water resource official Zaki Karim.

In a country ravaged by decades of conflict, with crumbling infrastructure and floundering public policies, residents already receive water intermittently.

The latest shortages are forcing even "stricter rationing" and more infrequent water distributions, Karim said.

In addition to going door-to-door to raise awareness about water waste, the authorities were also cracking down on illegal access to the water network.

In the province of roughly two million inhabitants, the aim is to minimize the impact on the provincial capital of Kirkuk.

"If some treatment plants experience supply difficulties, we will ensure that there are no total interruptions, so everyone can receive their share," Karim said.
