wads of mysteriously dense blobs — including one surprisingly barker - shaped structure — are lurking beneath an ancient seabed surroundingMars ' north pole , a new " gravity map " of the Red Planet reveals . The first - of - its - kind atlas also confirms a late determination about Mars ' tallest mountain that could help reveal secrets about the planet ’s volcanic past and present .
In a newfangled study , researchers created the first true global density mapping of Mars by combine information about the planet ’s freshness fromNASA ’s InSight lander with track record of fluctuations in the orbits of satellites , such as NASA ’s Mars Reconnaissance Orbiter and theEuropean Space Agency ’s Mars Express , as they were pulled out of place by obscure gravitational anomaly .
The new global density map of Mars has revealed 20 surprisingly dense blobs beneath the planet’s north pole, and one of them looks like a dog, researchers say.
The standout features in the unexampled map were 20 underground blob in the Borealis Basin in Mars ' northerly hemisphere , which was an ancient seabed more than 3 billion years ago . These blobs add up in a mountain range of shapes and sizes , including one that " resembles the shape of a dog , " and have denseness between 300 and 400 kg per cubic meter eminent than the surrounding ground , the researcher drop a line in astatement .
However , it is presently indecipherable what these blob are , why they are so dense or how they were created .
" These dumb bodily structure could be volcanic in origin or could be compacted material due to ancient [ meteor ] impacts , " subject field principal authorBart Root , a planetary scientist at Delft University of Technology in the Netherlands , sound out in the program line . And " there seems to be no trace of them at the control surface , " he add up .
The super dense blobs come in a range of shapes and sizes that scientists cannot currently explain.
The teampresented their findingsat the Europlanet Science Congress , which was admit in Berlin Sept. 8 - 13 .

The new map also confirmed the presence of amassive 1,100 - Swedish mile - wide ( 1,750 kilometers ) blob under Olympus Mons , a dormant volcano near Mars ' equator that , at more than 16 mi ( 25 km ) above the major planet ’s Earth’s surface , is thesolar system’stallest pile .
This mammoth blob , which wasfirst observe in 2022 , is less dense than its environs and is most probable a massive plume of cooled lava , hinting that Mars ' volcanism may have terminate only lately orcould be ongoing .
The fresh mapping of the Olympus Mons blob could also shed light on the border Tharsis plateau , an elevated region of Mars that ishome to the planet ’s tallest volcanoes , as well as other challenging geological structures , such as therecently mapped " Labyrinth of Night " canon .
The newly mapped blobs are not the only interesting objects found under the Red Planet ’s surface recently .

In January , NASA satellite revealed a 2 - mile - thick ( 3.2 kilometer ) level of iceburied beneath Mars ' equator . And in August , scientists announced themajor discovery of an enormous obscure sea — with enough water to cover the major planet with 1 naut mi ( 1.6 kilometre ) of piss — trapped deep below the Red Planet ’s surface .
The sketch author are among a group of scientists pop the question a Mars mission acknowledge as theMartian Quantum Gravity ( MaQuls ) , which would flee twin spacecraft around the Red Planet , allowing researchers to more accurately measure concealed gravitative anomalies . The MaQuls foreign mission was alsorecently discussedat the Europlanet Science Congress but has not been approved by any bureau .
