Júnior Silva (Schwarza)'s contact route, audience split and rate estimates are ready — members see them in one tap.
Júnior Silva, professionally known as Schwarza, is a Brazilian science communicator who transitioned from a background in graphic design to full-time education. He developed a deep interest in the cosmos and realized there was a lack of accessible Portuguese-language content regarding space. Over the years, he has established himself as a trusted voice in the Brazilian scientific community, bridging the gap between academia and the public.
Schwarza's breakthrough occurred through his YouTube channel, 'Canal do Schwarza,' which gained significant traction by covering high-profile space missions and astronomical events in real-time. His ability to explain complex topics like black holes and quantum mechanics using simple analogies resonated with millions. This digital success eventually led to the publication of his acclaimed book, 'Almanaque do Espaço,' which solidified his reputation as a formal educator.
His content is characterized by a mix of high-quality visual production and deep technical research, often presented with his signature catchphrase 'Scalobaloba.' He primarily posts deep dives into recent NASA discoveries, updates on SpaceX developments, and explanations of physics paradoxes. On Instagram, he shares bite-sized science facts, behind-the-scenes looks at his writing process, and commentary on current tech trends.
Beyond digital content, Schwarza has successfully ventured into the publishing industry with multiple books focused on space and science. He frequently collaborates with educational platforms and tech brands that align with his mission of scientific literacy. Additionally, he earns revenue through speaker engagements at major Brazilian technology and education events, as well as through his own line of space-themed merchandise.
There is no reliable public estimate for Schwarza's total net worth, as his financial details remain private. His income is diversified through YouTube ad revenue, book royalties, and strategic brand partnerships with technology companies. He also generates revenue through public speaking appearances and his participation in various educational projects across Brazil's digital landscape.
Schwarza is best known for his literary work, most notably the book 'Almanaque do Espaço,' which serves as a comprehensive guide to the universe. He has also released 'Do Meio ao Fim,' which explores the history and future of the planet and humanity. His digital presence serves as a recurring 'video encyclopedia' for students and science enthusiasts across the Lusophone world.
Fans can primarily find his long-form educational videos on his YouTube channel, Canal do Schwarza. For daily updates, science news, and personal insights, he is highly active on Instagram under the handle @schwarza79. He also maintains a presence on other social platforms and frequently appears as a guest expert on Brazilian podcasts and news segments regarding space.
Schwarza has achieved several major milestones in his career, including surpassing 180,000 followers on Instagram and building a YouTube community of over one million subscribers. He has been recognized as a top influencer in the 'Education' category by various Brazilian digital media awards. His books have also achieved significant sales milestones, becoming staple resources for introductory astronomy in Brazil.

Related questions
Júnior Silva (Schwarza) is based in Brazil and posts in Portuguese. For brands that usually means the core audience follows the same market and language, with a long tail from everywhere else — big accounts rarely stay local.
The content sits in education and tech & science, so the people watching are self-selected for those interests. That is the useful part of a niche profile: a mid-size account inside the right category often beats a much larger general account, because the audience already cares about the subject.
If you need the same audience profile in another market, the country and language lists on CreatorFanBase let you line up comparable creators side by side instead of guessing.
If you are shortlisting Júnior Silva (Schwarza) for a campaign, these are the facts worth carrying into the brief. Everything here is stored data, refreshed on a schedule rather than typed in once.
A practical sequence: check the lead platform matches where your buyers are, check market and language, open the official account to see recent posting frequency, then ask for a media kit and rate card directly.

Júnior Silva (Schwarza)'s counts come from the platforms themselves via instagram public profile and are refreshed on a schedule; the most recent check was Oct 16, 2026. When a platform blocks a read, we keep the last verified number and show where it came from instead of filling the gap with an estimate.
Large jumps are treated as suspect: a sudden drop past our safety threshold is held back for review rather than published, which is why the numbers here tend to be lower-drama than screenshots circulating elsewhere.
